Abstract

We report the first study of optical planar and channel waveguides fabricated in the new nonlinear crystal Ca4YO(BO3)3 by use of MeV He+-implantations. The n x, n y, and n z refractive index modifications are studied. Losses in nonannealed YCOB waveguides measured with a CCD camera are found to be less than 2 dB cm-1. This work is the first step toward the investigation of frequency conversion within the obtained guiding structures.
