    摘要: A metal-semiconductor-metal (MSM) device couples light from an optical mode in a waveguide to a surface plasmon polarition (SPP) mode on an electrode surface of the MSM device. Once in an SPP mode, the absorption of light in the semiconductor can take place in a very small area. This may allow for a shrinking of the active detector area and allow for low capacitance, very short transit distance for the electrical carriers and allow for very low voltage devices and/or very high frequency.

    摘要: Embodiments of the present invention describe a waveguide-based photodetector device and its methods of fabrication. The waveguide photodetector device comprises a substrate having a cladding structure formed thereon. A waveguide element for receiving optical signals is disposed within the cladding structure. A portion of the waveguide element is encapsulated by a photodetector element that detects the optical signal received by the waveguide element and generates an electrical signal based on the optical signal. Encapsulating the waveguide element in the photodetector element improves coupling efficiency and enables a waveguide photodetector device with higher speeds and higher responsivity.

    摘要: A semiconductor based structure containing substantially smoothed waveguides having a rounded surface is disclosed, as well as methods of fabricating such a structure. The substantially smoothed waveguides may be formed of waveguide materials such as amorphous silicon or stoichiometric silicon nitride. The substantially smoothed waveguides are formed with an isotropic wet etch combined with sonic energy.

    摘要: An apparatus and method for embedding a laser source on a semiconductor substrate and an optical interconnect to couple the laser source to internal components of the semiconductor substrate. An on-die waveguide is integrated on the semiconductor substrate. A package waveguide is disposed on the semiconductor substrate and evanescently coupled to the on-die waveguide. The laser source is embedded within the packaged waveguide to provide an optical signal to the on-die waveguide via the package waveguide.
