Paper Abstract

A novel, compact 48-channel optical transceiver module has been designed and fabricated based on a "holey" Optochip - a single-chip CMOS transceiver IC with 24 receiver and 24 laser driver circuits each with a corresponding throughsubstrate optical via (hole). The holes enable 24-channel 850-nm VCSEL and photodiode arrays to be directly flip-chip soldered to the CMOS IC to maximize high-speed performance and facilitate direct fiber-coupling to a standard 4 x 12 MMF array. The Optochips were packaged into complete modules by flip-chip soldering to high-density, high-speed organic carriers. All 48-channels showed good performance up to 12.5 Gb/s/ch providing a 300 Gb/s bidirectional aggregate data rate.
