INTEGRATED OPTIC PRINT HEAD

摘要

An integrated optics print head includes an array of independently driven semiconductor lasers disposed on a common substrate with their outputs coupled to an integrated waveguide structure. The integrated waveguide structure includes a multiplicity of "S" shaped, low-loss waveguides which have substantially the same length. Further, in order to reduce crosstalk, the region of the waveguide structure at the output where all the waveguides are in close proximity is made as short as possible while maintaining a parallel relation between the waveguide outputs.
