Synthesis of highly integrated optical network based on microdisk-resonator add-drop filters in silicon-on-insulator technology

We analyze a highly compact optical add-drop filter topology based on a pair of microdisk resonators and a bus waveguide intersection. The filter is further assessed on an integrated optical 4 x 4 network for optical on-chip communication. The proposed network structure, as compact as 50 x 50 mu m, is fabricated in a CMOS-compatible process on a silicon-on-insulator (SOI) substrate. Finally, the experimental results demonstrate the proper operation of the fabricated devices. (c) 2009 Society of Photo-Optical Instrumentation Engineers. [DOI: 10.1117/1.3242841]
