New Features
Purge feature
Due to the high resolution and sensitivity of the AQ6376E, it can actually detect the presence of water molecules in the air. The water vapor is detected in the upper Near-IR wavelength region and could overlap with or mask the spectral characteristics of the actual device under test in that particular region.
By continuously supplying a pure purge gas such as nitrogen to the monochromator through the ports on the back panel, the AQ6376E can reduce the influence of water vapor absorptions and provide more reliable and accurate measurements than ever before.
Built-in cut filter for high order diffracted light
Due to the diffractive technology used, the monochromator in some circumstances could generate high order diffracted light, which appears at wavelengths equal to the integral multiple of input wavelengths.
By cutting incoming light below 1500 nm with the built-in filter, the AQ6376E drastically reduces the influence of high order diffracted light on the measurement. Thus, the measured data are always reliable and replicate the real signal under test.
Double speed mode
Increases the sweep speed up to 2 times compared to the standard sweep mode, with only a 2 dB penalty to the standard sensitivity value.
Long Wavelength Range: from 1500nm to 3400nm
The AQ6376E covers not only the wavelength span used in communications, but also the 3µm region which is used for environmental sensing, medical, biology and industrial applications.
High Sensitivity: down to -65dBm
The AQ6376E can measure optical power from +13dBm down to -65dBm thanks to its high-dynamic and very low noise components and circuits used for photo detection. This enables precise measurements of both high power and low power sources.
Measurement sensitivity can be chosen among 7 values according to the measurement speed required by the specific test to be performed.
High Resolution & Wide Dynamic Range
The AQ6376E uses a double-pass monochromator structure to achieve high wavelength resolution (0.1 nm) and wide close-in dynamic range (55 dB). Thus, closely allocated signals and noise can be separately measured.
High speed Measurement
GREATER EFFICIENCY
High Speed Sweep
With a proprietary sweep technique the AQ6376E achieves a much faster sweep speed than conventional measurement systems, which use a monochromator. Max. sweep time is only 0.5 sec. for 100 nm span.
Fast command processing and data transfer
Applying a fast microprocessor, the AQ6376E achieves very fast command processing speed and Ethernet interface provides up to 100 times faster data transfer speed than GP-IB.
Fast auto-calibration
The AQ6376E has a built-in reference light source for wavelength calibration and optical alignment of the monochromator components, allowing it to deliver always-accurate measurements.
The calibration and alignment process takes less on the unit take than 2 minutes and is fully automatic.
NOTE: The wavelength calibration can also be performed by using an external reference source.
Free-Space Optical Input
• WORRY-FREE, as no internal fiber can be scratched or get dirty
• MAINTENANCE-FREE, as no internal fiber has to be cleaned
• VERSATILE, as the instrument accepts both /PC and /APC connectors
• DUAL PURPOSE, as the instrument accepts both Single-Mode and Multi-Mode fibers without being affected by the high insertion loss from MM-SM fibers matching
The AQ6376E uses a free-space optical input structure, i.e. no fiber is mounted inside the instrument.
This smart solution is:
DUT-oriented test apps simplify the test process
The appplication mode (APP) transforms an OSA into a versatile machine dedicated to a device under test (DUT). APP mode provides a DUT-specific user interface that navigates the user from configuration settings to test result output without worrying with other OSA settings. The AQ6376E comes pre-installed with several standard applications including DFB-LD testing, FP-LD testing and SC light source testing. Additional optional applications are available for download from the Yokogawa Test&Measurement website.

The AQ6376E is the right instrument to test & characterize
Moreover, its peculiar characteristics and high-level performance make the AQ6376E the ideal OSA to measure gas concentration in the air using Laser Absorption Spectroscopy.
Passive and active devices characterization
Characterization of Fiber Bragg Gratings (FBGs)
A Fiber Bragg Grating (FBG) is a type of distributed Bragg reflector constructed in a short segment of optical fiber that reflects particular wavelengths of light and transmits all others. This is achieved by creating a periodic variation in the refractive index of the fiber core, which generates a wavelength specific dielectric mirror. An FBG can therefore be used as an inline optical filter to block certain wavelengths, or as a wavelength-specific reflector.
Fiber Bragg gratings can then be used also as direct sensing elements for strain and temperature, in fact the Bragg wavelength of the FBG can be tuned by strain and temperature change applied by a piezoelectric transducer. Specifically, fiber Bragg gratings are finding uses in instrumentation applications such as seismology, pressure sensors for extremely harsh environments, and as downhole sensors in oil and gas wells for measurement of the effects of external pressure, temperature, seismic vibrations and inline flow measurement.
Fiber Bragg gratings are created by "inscribing" or "writing" systematic (periodic or aperiodic) variation of refractive index into the core of a special type of optical fiber using an intense ultraviolet (UV) sources such as KrF or ArF excimer lasers.
However, the functional wavelength of FBG is not the writing wavelength, and for non-communication applications mentioned above (strain and temperature sensors) FBGs tuned on 2-3µm region are used. For testing such FBGs, the AQ6375E and/or AQ6376E are the ideal instruments depending on the wavelengths.
Characterization of Supercontinuum Light Sources
Supercontinuum light is generated by promoting highly nonlinear optical processes in special materials, e.g. photonic crystal fiber, by pumping them with a mode-locked pulsed laser (typically a femtosecond Ti:Sapphire laser).
Supercontinuum light can be best described as ‘broad as a lamp, bright as a laser', in fact it matches the characteristics of incandescent and fluorescent lamps - i.e. very broad spectrum - with the characteristics of lasers - i.e. high spatial coherence and very high brightness, which enables optimum coupling to a fiber and outstanding single-mode beam quality.
The Supercontinuum light sources are nowadays finding applications in a diverse range of fields, including optical coherence tomography, frequency metrology, fluorescence lifetime imaging, optical communications, gas sensing and many others.
Detecting the multi-wavelength optical pulses generated by a Supercontinuum light sourcewith AQ6376E.
AQ6376E, thanks to its premium performance, is the right instrument to tests and characterize Supercontinuum light sources during their production and after-production quality check processes.
Characterization of Lasers used in Medical applications
Specific LASERs emitting around 2µm are used nowadays as tools for endoscopic surgery, like Thulium laser used for surgical treatment of prostate cancer.
AQ6376E is the best instrument to test and characterize such kind of LASERs during their production and after-production quality check processes.
Gas detection by Laser Absorption Spectroscopy
The global warming gases, called greenhouse gases, like CO2, SO2, NOX and CH4, has strong absorption lines in the 2 to 3 µm wavelength region. The presence and concentration of those gases in the atmosphere can be determined by measuring the optical absorption spectrum of the gas mixture under test.
Thanks to its Free Space Optical Input, the AQ6376E can also measure the absorption spectrum of an air column using the Sun as light source and transferring by a MultiMode fiber the light passed-through the mixture.
Cavity Ring-Down Spectroscopy applications (CRDS)
CRDS is a highly sensitive optical spectroscopic technique that enables measurement of absolute optical extinction by samples that scatter and absorb light. It has been widely used to study gaseous samples, which absorb light at specific wavelengths, and in turn to determine mole fractions down to the parts per trillion level. The technique is also known as cavity ring-down laser absorption spectroscopy (CRLAS).
A typical CRDS setup consists of a laser that is used to illuminate a high-finesse optical cavity, which in its simplest form consists of two highly reflective mirrors. When the laser is in resonance with a cavity mode, intensity builds up in the cavity due to constructive interference. The laser is then turned off in order to allow the measurement of the exponentially decaying light intensity leaking from the cavity. During this decay, light is reflected back and forth thousands of times between the mirrors giving an effective path length for the extinction on the order of a few kilometers.
If something that absorbs light is placed in the cavity, the amount of light decreases faster-it makes fewer bounces before it is all gone. A CRDS setup measures how long it takes for the light to decay to 1/e of its initial intensity, and this "ringdown time" can be used to calculate the concentration of the absorbing substance in the gas mixture in the cavity.
Cavity ring down spectroscopy is a form of laser absorption spectroscopy. In CRDS, a laser pulse is trapped in a highly reflective (typically R > 99.9%) detection cavity. The intensity of the trapped pulse will decrease by a fixed percentage during each round trip within the cell due to both absorption and scattering by the medium within the cell and reflectivity losses.
One of the major applications of CRDS is breath analysis:
The following graph shows the spectra of the biomarker hydrogen cyanide (HCN) along with water vapor (H2O) at atmospheric pressure and at concentrations typically found in exhaled human breath:
The AQ6376E has the right characteristics to be an effective instrument to measure the output of CRDS systems.
