title: Optical planar and channel waveguides in the new nonlinear crystal Ca4YO(BO3)3 (YCOB) fabricated by He+ implantation.
abstract: We report the first study of optical planar and channel waveguides fabricated in the new nonlinear crystal Ca4YO(BO3) by use of MeV He+-implantations. The nx, ny, and nz 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.
