Abstract
A simple OADM based on X-crossing InGaAsP/InP vertical coupler filters is demonstrated. Laterally separated input and output waveguides is achieved using wafer bonding technique and double side wafer processing. Sidelobe level of -26dB and coupling efficiency of 97% are achieved for an OADM with X-crossing angle of 0.25 ° .
