    摘要: A method of reducing the scattering losses that involves smoothing of the core/cladding interface and/or change of waveguide geometry in high refractive index difference waveguides. As an example, the SOI-based Si/SiO2 waveguides are subjected to an oxidation reaction at high temperatures, after the waveguide patterning process. By oxidizing the rough silicon core surfaces after the patterning process, the core/cladding interfaces are smoothened, reducing the roughness scattering in waveguides.

    摘要: An integrated device includes a waveguide, which may be connected to a photonic circuit and an external fiber, and an on-chip device formed on an optical chip by forming a region in which the waveguide terminates. The region is bounded by reflective surfaces. Light coming from the waveguide is essentially trapped inside the region and directed to an on-chip device disposed in the region. An integrated device consists of a low index difference waveguide, an on-chip mode converter, a high index difference waveguide, and an on-chip function formed on a single optical chip so that the high index difference waveguide is close to the substrate surface upon which the mode converter is formed. Substrate surface height differences are provided to define different substrate surface mounting heights for a low index difference waveguide, high index difference waveguide, a mode converter, and an on-chip device. The height differentials provide close proximity of components allowing on-chip devices, such as a Ge detector or electronics, to be integrated on a chip with the high index difference waveguide that is connected to a mode converter.

    摘要: The invention features a programmable optical chip. The optical chip has a plurality of optical functions, each of which is connected to a waveguide having a core and a cladding. A photosensitive layer is disposed between at least three of the waveguides, and the photosensitive layer has a refractive index similar to that of the cladding prior to exposure to irradiation. The photosensitive layer changes refractive index upon exposure to irradiation to selectively form an optical connection between at least two of the waveguides.

    摘要: Methods of tuning, switching or modulating, or, in general, changing the resonance of waveguide micro-resonators. Changes in the resonance can be brought about, permanently or temporarily, by changing the size of the micro-resonator with precision, by changing the local physical structure of the device or by changing the effective and group indices of refraction of the mode in the micro-resonator. Further changing the asymmetry of the index profile around a waveguide can alter the birefringence of the waveguide and allows one to control the polarization in the waveguide. This change in index profile may be used to change the polarization dependence or birefringence of the resonators.
