Realization of a Multichannel Chemical and Biological Sensor Using 6x6 Multimode Interference Structures

Trung-Thanh Le

Abstract—A new mirroring resonators (MRR) based on 6x6 multimode interference (MMI) couplers for multichannel and highly sensitive chemical and biological sensors is proposed in this paper. The proposed sensor structure has advantages of compactness, high sensitivity compared with the reported sensing structures. By using the transfer matrix method (TMM) and numerical simulations, the designs of the sensor based on silicon nanowires are optimized and demonstrated in detail.

Index Terms—Biological sensors, chemical sensors, optical microring resonators, high sensitivity, multimode interference, transfer matrix method, beam propagation method
