MONOLITHIC INTEGRATION OF MQW MODULATORS ON AN OPTICAL MULTIPLEXER ONINP FOR 100 GB S TRANSMISSION/

We report on an InP-based optical multiplexer integrated with high-spe ed multiquantum-well (MQW) electroabsorption modulators for 100 Gb/s t ransmission. The optical multiplexer is based on a multimode interfere nce (MMI) splitter, a waveguide array, and a taper-type combiner desig ned using beam propagation method (BPM), The modulators are integrated on the top of the optical multiplexer. The integrated device is fabri cated by three step epitaxy using metal organic vapor phase epitaxy (M OVPE) and by dry etching, The static and dynamic performances are meas ured, leading to the generation and the modulation of a 100 GHz optica l pulse train, This optical pulse train is also coded using a pseudora ndom nonreturn to zero (NRZ) pattern.
