Abstract
An optical transceiver includes optical circuitry disposed on a substrate and comprising a transmitter and a receiver. The circuitry includes least one multi-mode interferometer (MMI), including a multi-mode waveguide comprising an input face and an output face, the input and output faces being bisected by a longitudinal axis, the multi-mode waveguide having a predefined width transverse to the longitudinal axis. Ports are coupled to respective waveguides and are configured to launch one or more input beams through the input face and receive one or more output beams from the output face. The ports include, on at least one of the faces, two or more ports at respective locations that are offset transversely from the longitudinal axis by at least λ/300 from respective base transverse displacements that are equal to integer fractions of the width.
