    摘要: An improved waveguide shuttle optical switch design which provides the function of a variable optical attenuator (VOA). A small degree of intentional misalignment of the waveguide will create different levels of optical attenuation. By finely controlling the misalignment of a selected switched position, a single device may be realized that will provide the functions of both switching and attenuating or just attenuation alone. The optical MEMS device utilizes a latching mechanism in association with a thermal drive actuator for aligning a waveguide shuttle platform. The integration of the switching function and the VOA function reduce the optical loss which is otherwise unavoidable when the inevitable alternative of a separate switch and a separate VOA must necessarily be employed. The resultant improved device can also be applied for correcting the difference in optical intensity created by the manufacturing tolerances inherent in the fabrication of array waveguide gratings.

    摘要: First and second ridge type photonic waveguides are provided. Each of the waveguides includes a core layer and a reflective cladding layer in continuous contact with a first side of a core layer. The core layer has a core index of the refraction and is formed in a ridge in a dimension and shape to impose lateral confinement. The reflective cladding layer has an index of refraction that is substantially different than the core index of refraction. An inter-waveguide slab portion is provided between the first and second waveguides. A substrate supports the first and second waveguides, the slab portion, and the reflective cladding layer. A light interceptor region is provided to hinder a transfer of photons between the first and second waveguides through the inter-waveguides slab portion. The light interceptor region may include a trench region, which is an air gap in one embodiment.

    摘要: A charge-coupled device (CCD) image sensor includes a layer of a semiconductor material having a first conductivity type. A horizontal CCD channel region of a second conductivity type is disposed in the layer of the semiconductor material. The horizontal CCD channel region includes multiple phases that are used to shift photo-generated charge through the horizontal CCD channel region. Distinct overflow drain regions are disposed in the layer of semiconducting material, with an overflow drain region electrically connected to only one particular phase of the horizontal CCD channel region.
