Abstract: Disclosed is a coherent optical combining photonic integrated circuit that can detect and align light amplified by a scalable quantity of semiconductor optical amplifiers (SOAs). The light can be split into beams and amplified by individual SOAs in a PIC and combined via couplers in the PIC. The combined light can be measured using a photodetector and the light beams can be adjusted based the photodetector measurement to coherently combine the light to achieve high optical power from the photonic integrated circuit.

Abstract: Embodiments of the invention are directed to an optical USB (OUSB) to enhance the data rate of USB by adding super-high data rate (e.g. 10 Gbps) optical communication on top of its current specification so that backward compatibility is achievable. Mechanical tolerances may be achieved by using embedded lenses to expand a beam emerging from the connector prior to entering its mating connector and using an identical lens in the mating connector to collimate the beam back onto a fiber.
