2022 Optical Fiber Communications Conference and Exhibition (OFC), 2022•ieeexplore.ieee.org… If a high-speed photodetector with a large aperture is developed, a very compact FSO
transceiver can be established for indoor FSO communication applications. In this paper,
we present a 400-pixel high-speed PD, which is an extended design from our previous
works [4-5]. We also discuss the demonstration of 25 Gbps FSO communication in 20 m free
space, using the fabricated large aperture (0.85 mm x 0.85 mm) 400-pixel PD. …

We fabricated a 400-pixel high-speed photodetector with a 0.85-mm large square size, while maintaining high frequency performance. The high frequency characteristics and optical alignment robustness in a 20 m long distance FSO communication was demonstrated.
