【 摘 要 】

References(8)Cited-By(3)We present details of a local high-index contrast silica waveguide that uses trenches filled with a low-refractive index material enabling bends with small radius to be used. The lateral relative refractive index difference was 8.34% and the minimum bend radius was 300µm. An 8-channel, 100GHz spacing compact arrayed-waveguide grating using waveguides with small bend radius was successfully fabricated.
