摘要: Arrangements (100) using air trench cladding (104, 106) enables minimization of the evanescent tail to suppress light coupling radiation modes, resulting in low-loss bends and splitters. Structures including sharp dends T-splitters without transmission loss, crossings crosstalk, couplers from/to fibers without-of-plane waveguides substantial loss are provided with such claddings. Air sidewall pushes tails toward top bottom claddings enhance between vertically positioned waveguides. Fabrication processes wafer bonding technology also provided.
