The substrate includes a plurality of electrical conductors electrically coupled to the plurality of beam directing devices. A low density interconnect is coupled to the conductive traces along a periphery of the substrate to interface drive electronics with the plurality of beam directing devices
Claims25
An optical switching core, comprising:
- a plurality of beam directing devices coupled to a substrate for redirecting a plurality of incoming optical beams to at least one of a plurality of output ports, wherein said substrate comprises a plurality of electrical conductors electrically coupled to said plurality of beam directing devices;
- and
- an interconnect coupled to said plurality of conductive traces along a periphery of said substrate to interface drive electronics with said plurality of beam directing devices.
An optical switching core, comprising:
- an input optical tile coupled to a first side of a frame, wherein said input optical tiles comprise a plurality of input beam directing devices coupled to a substrate for redirecting a plurality of incoming optical beams to at least one of a plurality of output ports, wherein said substrate comprises a plurality of electrical conductors electrically coupled to said plurality of input beam directing devices and an input interconnect coupled to said plurality of conductive traces along a periphery of said substrate to interface drive electronics with said plurality of input beam directing devices;
- an output optical tile coupled, to a second side of said frame, wherein said output optical tiles comprises a plurality of output beam directing devices coupled to an output substrate for directing said plurality of redirected optical beams received from said input tile to at least one of a plurality of output ports;
- and
- one or more sets of drive electronics mechanically coupled to said frame and electrically coupled to said input interconnect for controlling said plurality of input beam directing devices.
An optical switching core, comprising:
- an input beam directing array, comprising one or more input optical tiles coupled to a first side of a frame;
- an output beam directing array comprising one or more output optical tiles coupled to a second side of said frame wherein said input optical tile redirects a plurality of incoming optical beams to at least one of a plurality of output ports in said one or more output optical tiles.
A method for fabricating an optical switching core comprising:
- fabricating first and second arrays of beam directing devices;
- passively assembling collimating optics on the first array and the second array;
- and
- assembling the first array and second array with the collimating optics on a frame, wherein the collimating optics and arrays are independently fabricated prior to assembly on the frame.
