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

Abstract

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 4×4 network for optical on-chip communication. The proposed network structure, as compact as 50×50μm, 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. © 2009 Society of Photo-Optical Instrumentation Engineers.
