Waveguide-Integrated Ge/Si Avalanche Photodetector with 105GHz Gain-Bandwidth Product
Avalanche photodiodes
2015/6/4
We report the first demonstration of a waveguide-integrated avalanche photodetector using Group-IV heterostructure materials. Such device achieved a responsivity of ~0.8A/W at unity gain and an impres...
High-Speed Near Infrared Optical Receivers Based on Ge Waveguide Photodetectors Integrated in a CMOS Process
High-Speed Near Infrared Optical Receivers Ge Waveguide Photodetectors Integrated CMOS Process
2009/5/19
We discuss our approach to monolithic intergration of Ge photodectors with CMOS electronics for high-speed optical transceivers. Receivers based on Ge waveguide photodetectors achieve a sensitivity of...
