Abstract
The present invention relates to a planar wave guide structure having a grating element fabricated thereon as well as a focusing element therein. The lens element of the present disclosure is preferably a void, to include air, a vacuum or other material which has an index of refraction less than an index of refraction of the core layer of the planar wave guide in which the lens element is disposed. The lens element is preferably fabricated by laser micromachining or other techniques described herein. The grating at the far end of the planar wave guide functions to separate wavelengths in the demultiplexing embodiment of the present disclosure, and as a wavelength integrator in the multiplexing embodiment of the disclosure of the present invention.
