Simplified EDFA testing
The request for lower uncertainties in power measurements are increasing,especially in the transformer industries. Their role is to ensure that the electricity is distributed in an efficient and reliable way.
Laval University is a research institution world renowned for optics and photonics technology research and training, and are the founders of The Center for Optics, Photonics, and Lasers (COPL).
The university's researchers needed a faster and more efficient and practical solution to measure the spectral performance of lasers and optics beyond traditional telecom wavelengths. To achieve this, they contacted Yokogawa Test&Measurement and collaborated to develop a breakthrough grating-based optical spectrum analyzer that could cover MWIR wavelengths up to 5.5 um. Click to learn how productivity in the research lab dramatically increased for precise characterization of laser sources, and active/passive optical components in the fields of communications, medical diagnosis, advanced optical sensing, and environmental and atmospheric sensing.
In this poster session research from The European Conference on Lasers and Electro-Optics 2017, researchers from Texas A&M University, Texas A&M University at Qatar, and Florida A&M University use a Yokogawa Test&Measurement AQ6376 Optical Spectrum Analyzer to detect methane in the air.
The extreme test requirements of our research called for an OSA with extended MIR spectrum bandwidth capabilities up to 5μm, but we couldn’t find one on the market capable of measuring optical inputs at these wavelengths. Yokogawa Test&Measurement rose to the challenge and developed a new OSA model for us that would. Not only do we now have an instrument that is practically custom-made for our needs, it provides repeatable, accurate, and trusted measurement outputs and is easy to learn and use. Their equipment and ability to create a new optical measurement solution has definitely increased the overall efficiency and productivity of our research team.

For those not able to couple light into a fiber, the use of a free space light measurement jig provides a means of measuring the properties of free space light (like wavelength, power, peaks, SMSR, noise, etc.) via an optical spectrum analyzer (OSA), something not typically viable. This video demonstrates the setup and use of an example jig to measure the output of a smartphone's LiDAR light.
A vision of self-driving cars propels the research and development of automotive LiDAR, a vital hardware providing distance and velocity information of a vehicle’s surroundings. Some LiDAR concepts are already heading toward production for automotive ADAS and industrial markets. Two newer concepts promise the greatest potential yet: frequency-modulated continuous wave (FMCW) LiDAR and time-of-flight (TOF) flash LiDAR. However, there are engineering challenges impeding their full adoption. This webinar reviews operation principles and challenges of different LiDAR concepts, a brief discussion on the LiDAR market, and a review of critical optical components such as photodetectors and sources.
Key takeaways include:
Increasing demands for greater network bandwidth and expansion of 5G wireless backhaul has driven data rates to 400G, 800G, and beyond. Starting with the physical layer of the optical network stack, precision measurement of these light speed signals is crucial.
This webinar covers a range of alternatives used to evaluate test parameters for DWDM, OSNR, SMSR, and EDFA, and includes a discussion on interesting applications like the use of high-energy lasers across space satellite mesh networks.
Key topics include:
Yokogawa Test&Measurement, a pioneer and leader in precision optical measurement, is pleased to announce that the latest addition to its optical spectrum analyzer line, the AQ6380 Highest Performance OSA has received the highest score, 4.5/5.0, in the Lab/Production Test Equipment class by 2022 Lightwave Innovation Reviews.
