摘要：
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. Then n(x), n(y), and n(x) 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. (C) 2004 Optical Society of America.
