  • Imaging laser diodes with a lightwave circuit
    Patent number: 8548286
    Abstract: A method for imaging light from a plurality of laser diodes (504) onto a multi-channel light valve (6) includes applying light from the plurality of laser diodes to a fiber waveguide (508) wherein each of the plurality of laser diodes is coupled to the fiber waveguide; guiding the light from the fiber waveguide through a planar lightwave circuit (PLC) (408) wherein light from the plurality of laser diodes is combined in the PLC; splitting the combined light in the PLC; and directing the split light from the PLC onto the multi-channel light valve.
    Type: Grant
