[Show abstract][Hide abstract] ABSTRACT: We developed a compact quadplex receiver for 100-Gbps Ethernet. High responsivity (0.74 A/W) is achieved for all channels using microlens-integrated photodiodes. The fabricated module was successfully operated at 25 Gbit/s with error free 10-km SMF transmission.
[Show abstract][Hide abstract] ABSTRACT: We describe an aspheric-microlens-integrated high-performance PIN photodiode, which exhibits high speed (35 GHz), high responsivity (0.8 A/W), and large alignment tolerance (26 mum) for direct coupling to a flat-ended standard single-mode fiber.
[Show abstract][Hide abstract] ABSTRACT: We developed a high-speed (over 30GHz) and high-responsivity (nearly 0.8A/W) back-illuminated PD with a newly developed high reflective reflector, and successfully demonstrated an error free 25-Gbps 10-km SMF transmission.
