High-Speed Resonant Microdisk Photodetectors Heterogeneouly Integrated To Si-Wire Waveguide
2008 IEEE PHOTONICSGLOBAL@SINGAPORE (IPGC), VOLS 1 AND 2(2008)
Abstract
Etched-mesa micro-disk resonant photo-detector heterogeneously integrated to Si-wire waveguide by oxide-to-oxide bonding has been proposed and analyzed by 3D-FDTD simulation. The 3um-, 5um- and 8um-diameter devices give free-spectral-ranges of 9.4THz, 5.8THz and 3.3THz, respectively. 3 mu m- and 5 mu m-diameter photo-detector potentially can give bandwidths better than 100GHz.
