Abstract : Disk type Ge-on-Si photodetector with an additional ring structure to enhance light absorption efficiency over Cband is proposed. The proposed photodetector has the average increment of 7.1 % and maximum increment of 13.1 % compared to ordinary disk type Ge-on-Si photodetectors with the same radius of 2 μm. Structure design is analyzed by FDTD (Finite Difference Time Domain) method. Keywords - Disk resonator, Germanium on Silicon photodetectors, Germanium micro disk, Ring resonator, Silicon photonics
