摘要： A method and system for multi-mode integrated receivers are disclosed and may include receiving an optical signal from an optical fiber coupled to a chip comprising a photonic circuit. The photonic circuit may comprise an optical coupler, one or more multi-mode optical waveguides, and a detector. The received optical signal may be coupled to a plurality of optical modes in the one or more multi-mode optical waveguides, which are communicated to a detector to generate an electrical signal from the communicated modes. The optical coupler may comprise a grating coupler. The chip may comprise a CMOS chip, and the optical fiber may comprise a single-mode or a multi-mode fiber. The detector may comprise a germanium or silicon-germanium photodiode, and/or a waveguide detector. The optical fiber may be coupled to a top surface of the chip and the multi-mode optical waveguides may comprise rib waveguides.
