Abstract:
Graphenes exceptional electrical and optical properties make it a promising candidate for ultrafast photodetectors in optical communication systems. This study investigates the design, fabrication, and performance characterization of graphene-based photodetectors operating in the near-infrared spectrum. Using chemical vapor deposition (CVD) grown graphene integrated with silicon waveguides, the photodetectors demonstrate a high responsivity, fast response time, and broad spectral bandwidth. Experimental results and simulation studies provide insights into the charge carrier dynamics and photoresponse mechanisms, indicating graphene�s potential to revolutionize high-speed optical networks
