We demonstrated 1310-nm 25-Gbps error-free transmission over both 2-km single-mode fibre and 100-m OM3 multi-mode fiber using the same silicon photonics transmitter and a high-sensitivity CMOS receiver with a lens-integrated photodiode.
A high-speed large-capacity optical printed circuit board (OPCB) for next-generation high-capacity routers and servers was developed. This OPCB is composed of a multilayer polymer optical waveguide, a receiver optical input/output (I/O) module (with a lens-integrated photodiode and a SiGe transimpedance amplifier), and a low-power (7.1 mW/Gb/s) transmitter optical I/O module consisting of a lens-integrated...
A low-power transceiver for optical interconnects, composed of 1.3-um-range microlens-integrated optical devices and CMOS ICs, was developed. It demonstrated 25-Gbit/s error-free transmission with over-100-m multi-mode fiber (MMF) and low-power consumption of 9 mW/Gbit/s.
We developed a high-speed (over 30 GHz) and high-responsivity (nearly 0.8 A/W) back-illuminated PD with a newly developed high reflective reflector, and successfully demonstrated an error free 25-Gbps 10-km SMF transmission.
An InAlAs-avalanche photodiodes (APDs) with gain-bandwidth (GB) product of 120 GHz suitable for 10 Gbit/s optical communication systems has been developed. With a SiGe-HBT preamplifier, the minimum sensitivity of -29.8 dBm was demonstrated
