ABSTRACT:
Optical devices and waveguides using a thin film optical waveguide having a two dimensional array of perturbations associated therewith or with adjacent optically coupled layers. The array is regular and forms periodic variations in two non-coincident directions which serve to reflect or scatter light waves into controllable transverse modes of propagation. Lasers as well as passive devices are disclosed.
