title: Low-loss LiNbO(3)waveguide bends with coherent coupling.
abstract: Low bending losses have been achieved in single-mode Ti:LiNbO(3) channel waveguides by utilizing coherent coupling effects between closely spaced abrupt bends. A variety of multiple-bend structures has been evaluated. Losses as low as 0.08 dB per coupled 1 degrees abrupt bend have been measured, as compared with 0.8 dB per isolated 1 degrees abrupt bend.
