Optical interconnect for switch applications
A switch module includes a switch integrated circuit (IC), a silicon photonics chips, and an interface having removably coupled first side and second side. The first side includes a lens array optically coupled to a SiP chip and the second side includes a connector having a plurality of planar lightwave circuits (PLCs) optically coupled to another lens array.
1. An optical connector for a silicon photonics chip, comprising:
a housing having an end cavity;
a plurality of lenses, arranged in a plurality of linear arrays forming a matrix, within the housing by the end cavity;
a plurality of planar lightwave circuits (PLCs), positioned within the housing in parallel next to one another and mounted on top of the lenses, to pass light to or receive light from the lenses, wherein some of the plurality of PLCs include at least one optical multiplexer and others of the PLCs include at least one optical demultiplexer, and wherein the optical multiplexer and the optical demultiplexer include arrayed waveguide gratings (AWGs); and
a plurality of optical fibers coupled to an opposing side of the PLCs, the opposing side being opposite a side of the PLCs mounted to the lenses.
2. The optical connector of claim 1 , where the plurality of lenses provide part of an expanded beam connector.
3. The optical connector of claim 1 , wherein the plurality of lenses are at a first opening of the housing.
4. The optical connector of claim 1 , wherein the housing is part of a cable.
