Abstract

A transceiver comprising a chip, a semiconductor laser, and one or more photodetectors, the chip comprising optical and optoelectronic devices and electronic circuitry, where the transceiver is operable to: communicate, utilizing the semiconductor laser, an optical source signal into the chip, generate first optical signals in the chip based on the optical source signal, transmit the first optical signals from the chip via a light pipe with a sloped reflective surface coupled to the chip, and receive second optical signals from the light pipe and converting the second optical signals to electrical signals via the photodetectors. The optical signals may be communicated out of and in to a top surface of the chip. The one or more photodetectors may be integrated in the chip. The optoelectronic devices may include the one or more photodetectors integrated in the chip. The light pipe may be a planar lightwave circuit (PLC).
