摘要:We report on the fabrication of the planar waveguides in the KNSBN crystal by using 17 MeV C5+ ions at a fluence of 2 x 10(14) ions/cm(2). After implantation, near surface regions of the crystal, there has a positive extraordinary refractive index (lie) change and the light inside the waveguides can propagate in a non-leaky manner. The two-dimensional modal profiles of the planar waveguides, measured by using the end-coupling arrangement, are in good agreement with the reconstructed modal distributions. The propagation loss for C5+ irradiated waveguide is similar to 0.8 dB/cm at 633 nm and similar to 0.72 dB/cm at 1064 nm. The waveguide gives good confinement of waveguide modes, which exhibits acceptable guiding qualities for potential applications in integrated optics. (C) 2013 Elsevier B.V. All rights reserved.
