The Smart-Pixel Optoelectronic Connections (SPOEC) project aims at the construction of a 64×64 channel optoelectronic crossbar interconnect to demonstrate optical data I/O to Si-CMOS at aggregate rates in excess to 1 Tbit/s. A schematic diagram of the layout is shown. The 64 channels are replicated using an 8×8 diffractive fanout and are imaged onto a hybrid flip-chip bonded Si/CMOS optoelectronic switching chip. Data are routed electronically from the InGaAs multiple quantum well (MQW) detectors by the custom Si circuitry to differential InGaAs-based MQW modulator pairs. The data is read from these modulators using Nd:YLF read beam and routed to an output chip composed of an 8×16 array of differential detectors.
