Ridge waveguide quantum-well wavelength division demultiplexing detector with four channels
Abstract
The authors report a four-channel wavelength-division-demultiplexing detector based on a reverse-biased GaAs/AlGaAs single-quantum-well graded index separate confined heterostructure laser having segmented contacts. They achieve better than -15-dB channel crosstalk for three-wavelength operation, and better than -10-dB crosstalk for four-wavelength operation. The optimum wavelength separation is 18 nm for three channels and 14 nm for four …
