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

摘要： A system includes a plurality of AWGs, wherein one of the AWGs receives an input signal. The AWGS are divided amongst a first selective group of the AWGs providing even-numbered channel outputs associated with an even-numbered selection of the input signal, and a second selective group of the AWGs providing odd-numbered channel outputs associated with an odd-numbered selection of the input signal. An interleaver arrangement includes a plurality of ring structures so as to provide appropriate filtering characteristics for the even-numbered channel outputs and odd-numbered channel outputs.

摘要： The light-guiding structure includes a waveguide structure that comprises a substrate and a low refractive index underclad material. The waveguide structure is oxidized to form an oxidized layer on a surface of the waveguide structure. The oxidized layer is isotropically etched after the reaction-limited oxidation regime is approaching the diffusion-limited regime and repeatedly oxidized and etched so that the waveguide structure is continuously oxidized in the reaction-limited regime, reducing the overall time of oxidation and volume of oxidized material so that the waveguide structure has its sidewall roughness reduced efficiently enabling high transmission rates of guided light.
