High-Responsivity Waveguide UTC Photodetector with 90 GHz Bandwidth for High-Speed Optical Communication

A directly coupled waveguide uni-traveling carrier photodetector (UTC-PD) with high responsivity and broad bandwidth is demonstrated. The device’s epitaxial structure was carefully optimized via optical simulations to enhance quantum efficiency. Furthermore, the fabrication process was refined to in...
