    摘要: The invention provides tunable delay or resonator devices in an electro optical substrate. Signals in at least one waveguide in the electro optical substrate pass through Y-junction reflectors which direct signals from one branch of the waveguide back into another branch of the waveguide. A coupled delay or resonator approximated loop is presented in an embodiment of the invention with opposing Y-junction reflectors. In other embodiments of the invention, a delay ladder is provided with selectable levels of delay from multiple outputs.

    摘要: A light source includes a hot electron source comprising a cathode that generates an electron beam and an anode comprising a germanium containing material positioned adjacent to the cathode. The anode is biased so that the electron beam accelerates towards the anode where some electrons are absorbed and then relax to both direct energy bands and indirect energy bands causing stimulation of low energy electrons from the indirect energy band to the direct energy band, thereby creating electroluminescence.

    摘要: A photodetector includes an optical distribution device having an optical input that receives an input optical signal and an optical waveguide grating coupler that converts the input optical signal from a longitudinal direction radiation mode to a surface-emitted radiation mode and that distributes the optical signal along a length of the optical waveguide grating coupler and emits the distributed optical signal from the surface. An optical detector includes an optical input that is positioned to receive the distributed optical signal emitted from the optical distribution device along a length the optical waveguide grating coupler. The optical detector generates a traveling wave RF signal. The optical distribution device reduces the optical power density of the input optical signal, thereby avoiding local saturation and damage to the optical detector.

A doping level of the semiconductor material being chosen to make the first and second waveguide conductive. A dielectric material is positioned in the slot which increases confinement of both an optical field and an electrical field inside the slot. A refractive index of the semiconductor material and a refractive index of the dielectric material positioned in the slot being chosen to reduce the Vπ·L product of the modulator.
