Integrated high-speed high-channel-count optical transceivers

Abstract

An optical link includes an optical transceiver. The optical transceiver includes an optical-emitter chip having multiple light sources configured to emit first optical signals in parallel, an optical-receiver chip having multiple photodetectors configured to detect second optical signals in parallel, and a circuitry chip having circuitry configured to control the optical-emitter chip and the optical-receiver chip. The optical-receiver chip is stacked between the optical-emitter chip and the circuitry chip.
