Abstract

Global interconnect on interposers between chiplets is currently mostly limited to nearest-neighbor communication. We propose an electro-optical router in 28nm on a photonic interposer to handle queuing and routing between dies and optical link drivers capable of 18ns link setup time for frame-level routing, with 1-to-6 lambda flexible wavelength capacity. Compact analog drivers and standard-cell-based SerDes and clocking achieve 0.007mm2 active area per link and 3.19pJ/b power.
