Active Wavelength Measurement Systems Based on Quantum Well Electroabsorption Devices

摘要

An active wavelength measurement system based on the use of a mesa type semiconductor quantum well electroabsorption filtering detector has been demonstrated. This system is suitable for many applications, including the demodulation of intracore Bragg grating fiber optic sensors. Average wavelength resolutions of better than +- 10 pm were achieved over a measurement range from 1555 to 1590 nm.
