Abstract
A novel waveguide photodetector with flat-top and steep-edge response is proposed in the paper. The response is obtained by designing a racetrack resonator following parallel-cascaded two or three micro-ring resonators. Its maximum values of the quantum efficiency in bandpass are 99.8%; 0.5dB, 3dB, and 20dB bandwidth is 0.22nm, 0.39nm, and1.1nm for cascaded double structure and 0.28nm, 0.32nm, and 0.5nm for cascaded triple structure, both of which meet the requirements of WDM system. Compared with similar waveguide photodetectors and RCE-PD, this photodetector has high quantum efficiency, narrow line width and good flat-top and steep-edge response. The structure is compact and conducive to chip-scale integration.
