Abstract:
1. A method for imaging light from a printhead onto a printing plate comprising: applying light from a plurality of laser diodes to an inlet waveguide such that there is a single laser diode for each waveguide having light coupled thereto; guiding the light from each waveguide through a planar lightwave circuit (PLC) having a plurality of inlet waveguides on a first side and a plurality of outlet waveguides on a second side; combining light from each of the inlet waveguides in the PLC; splitting the combined light in the PLC into a plurality of outlet waveguides; directing the split light from the PLC from each of the plurality of outlet waveguides on a multi-channel light valve; modulating light from each of the outlet waveguides with the multi-channel light valve according to image data; and creating an image on the printing plate.
