The paper reports the first deployment of graphene as a photo-detection element in a 10 Gbits/s optical data link. The authors developed an interdigitated metal-graphene-metal (MGM) photodetector with an asymmetric metallization scheme to enhance the efficiency of light detection. This design allows for efficient photo-detection across the entire illuminated area. The device achieved a maximum external photo-responsivity of 6.1 mA·W⁻¹ at a wavelength of 1.55 μm, a significant improvement over previous demonstrations. The unique band structure and electronic properties of graphene enable high-speed photodetectors with an ultra-wide operational wavelength range from 300 nm to 6 μm. The authors also demonstrated error-free detection of the optical bit stream in a 10 Gbits/s optical data link, highlighting the potential of graphene in various light detection applications. The paper includes detailed experimental results and simulations to support these findings.The paper reports the first deployment of graphene as a photo-detection element in a 10 Gbits/s optical data link.
