Two-dimensional optical interconnection based on two-layered optical printed circuit board

Abstract

The demonstration of an optical platform based on an optical printed circuit board (OPCB) was shown for two-dimensional (2-D) chip-to-chip optical interconnection. The optical platform was designed for 96 Gb/s total throughput which was 2 layers x 4 channels x 4 parallel links x 3 Gb/s/ch and using a passive assembly technology. We fabricated three main components for the 2-D optical interconnection; two-layered six-channel fiber- and connector-embedded OPCB, two-layered six-channel 90 degrees-bent fiber connectors, and 2-D optical transmitter/receiver (Tx/Rx) modules. The total optical loss from the Tx to the Rx was measured to approximately be -5.3 dB. The optical interconnection using an optical platform was successfully achieved with 3-Gb/s/ch data transmission.
