Paper Abstract

In this paper, we proposed a novel photodetector composed of cascaded microring resonators on silicon-on-insulator. In order to enhance the tolerance of signal wavelength drifting in optical communication, the photodetector was designed with a flat-top steep-edge response. In the photodetector, we used polarization insensitive cascaded silicon microring resonators as optical filter cavity, and used a silicon racetrack resonator bonded in p-i-n chip as optical detecting cavity. We used finite element (FE) mode solver, finite different time domain (FDTD), and transfer matrix method (TMM) to simulate the behavior of the polarization insensitive optical filter. With optimized parameters, the photodetector showed high quantum efficiency, narrow line width, and flat-top steep-edge.
