In research published on IEEE Xplore, researchers from Harbin Engineering University, the University of Limerick, and the Technological University Dublin use a Yokogawa Test&Measurement AQ6370C Optical Spectrum Analyzer to measure wavelengths when fiber is subjected to temperature changes.
In a research paper published in Optics Letters on the Optica (OPG) website, researchers from Harbin Engineering University, the University of Limerick, and the Technological University Dublin use a Yokogawa Test&Measurement AQ6370C Optical Spectrum Analyzer to test fiber components for potential use in integrated optical sources, including lasers.
University of Central Florida researcher uses a Yokogawa Test&Measurement AQ6370B Optical Spectrum Analyzer to map the properties of a new silicon waveguide fiber.
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.
