Integration of grating couplers with a compact photonic crystal demultiplexer on an InP membrane

Abstract : We demonstrate the integration of a 30% efficient grating coupler with a compact photonic crystal wavelength demultiplexer (DeMUX). The DeMUX has seven output channels that are spaced 10 nm apart and is aimed at coarse WDM applications. The integrated devices are realized on a high-index-contrast InP membrane using a simple benzocyclobutene wafer bonding technique. Cross talks of −10 to −12 dB for four channels 20 nm apart are obtained without optimization.
