Design considerations in optical add/drop multiplexers based on grating-assisted null couplers
The performance of a fully optimized optical add/drop multiplexer (OADM), based on null couplers and tilted Bragg gratings, is studied in detail. It is shown that maximization of the device performance involves three main optimization steps. First, the waveguide asymmetry (V2 /V1 ratio) should be op...
