Wavelength measurement system for Bragg fiber optic sensors using a quantumwell electroabsorption photodetector

摘要

A wavelength measurement system based on a quantum well electroabsorption photodetector is demonstrated and used to monito ra Bragg fiber optic sensor. A bandwidth limited wavelength resolution of +-3.62 pm/sq rootHz for a 1553.5 nm BFOS. A total accessible wavelength range of 90 nm was demponstrated for the system, making the system well suited for wavelength multiplexing applications.
