Abstract

A wavelength measurement system based on a quantum well electroabsorption photodetector is demonstrated and used to monitor a Bragg fiber optic sensor. A bandwidth limited wavelength resolution of +/- 3.62 pm/(root)Hz was achieved, corresponding to a strain resolution of +/- 3.02 (mu) (epsilon) /(root)Hz for a 1553.5 nm BFOS. A total accessible wavelength range of 90 nm was demonstrated for the system, making the system well suited for wavelength multiplexing applications.
