Low-loss LiNbO(3)waveguide bends with coherent coupling.

Low bending losses have been achieved in single-mode Ti:LiNbO3 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° abrupt bend have been measured, as compared with 0.8 dB per isolated 1° abrupt bend.
