Abstract

We propose what is, to our knowledge, a novel technique for fabricating a segmented waveguide by optical irradiation in a photorefractive LiNbO3:Fe crystal. The waveguide consists of many localized high-refractive-index regions that are fabricated by illumination of a focused laser beam. We fabricate straight, curved, and Y-branch waveguides. In the straight waveguides the transmitted power of a guided beam as a function of the period of segmentation and the dark decay time are measured. The tolerance for fabrication errors is also investigated both experimentally and numerically. The fabricated waveguide can be optically modified. We demonstrate that a curved structure can be transformed into a Y-branch structure.
