Abstract

A 4-channel phased-array wavelength division demultiplexer with 1.8 nm channel spacing at 1.54μm has been monolithically integrated with photodetectors in InP/InGaAsP. On chip losses are 3.5 to 4.5 dB. These are the lowest losses reported so far for demultiplexers monolithically integrated with photodetectors. Nearest neighbor crosstalk ranges from -12 to -21 dB.
