Microchannel-based optical backplane demonstrators using FET-SEED smart pixel arrays

摘要

Abstract: We have demonstrated a representative portion of an optical backplane using FET-SEED smart pixels and free-space optics to interconnect printed circuit boards (PCBs) in a two board, unidirectional link configuration. Four $MUL four arrays of FET-SEED transceivers were designed, fabricated, and packaged at the PCB level. The optical interconnection was constructed using diffractive micro-optics, and custom optomechanics. The system was operated in two modes, one showing high data throughput, 50 MBit/sec, and the other demonstrating large connection densities, 2222 channel/cm$+2$/. !12
