Optical transceiver with multimode interferometers - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240022329 titled 'Optical transceiver with multimode interferometers
Simplified Explanation
The abstract describes an optical transceiver that consists of optical circuitry on a substrate, including a transmitter and a receiver. The circuitry includes at least one multi-mode interferometer (MMI) with a multi-mode waveguide that has an input face and an output face. The input and output faces are divided by a longitudinal axis, and the waveguide has a predefined width perpendicular to the longitudinal axis. Ports are connected to the waveguides and are designed to launch input beams through the input face and receive output beams from the output face. The ports on at least one of the faces have two or more ports at different locations that are offset from the longitudinal axis by a certain fraction of the width.

Original Abstract Submitted
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 �/300 from respective base transverse displacements that are equal to integer fractions of the width.
