Abstract
An apparatus for imaging light from a plurality of laser diodes (504) onto a multi-channel light valve (6) includes a plurality of laser diodes each coupled to at least one fiber waveguide (508). A planar lightwave circuit (408) is coupled to at least one waveguide on a first side (508), and to the multi-planar light valve (6) on a second side.
Claims7
A system for imaging light from a printhead onto a printing plate comprising:
- a plurality of laser diodes;
- a planar lightwave circuit (PLC) having a plurality of inlets on a first side, each inlet connected to a laser diode comprising:
- a combiner that receives light from the plurality of inlets and combines the light from the plurality of inlets;
- a splitter that receives light from the combiner and splits the light into a plurality of outlet waveguides;
- directing light from each of the plurality of waveguides on a multi-channel light valve and wherein said outlet waveguides are selected or deselected by said multi-channel light valve according to image data;
- and
- creating an image on the printing plate with the light valve.
