    Abstract: An optical apparatus consisting of a laser for producing a coherent polarized beam of electromagnetic radiation of a preselected wavelength. A substrate of silicon has a first transparent cover layer for receiving the polarized beam substantially normally incident thereto, and a second transparent guide layer for receiving the polarized beam from the first layer and for supporting at least one resonant mode. The first and second layers have a preselected index of refraction and a grating is interposed between them, having a grating period less than half the preselected wavelength. The layers and grating interact to produce a standing wave resonance by Bragg reflection. A control obtains a resonance wavelength in the guide layer equal to the predetermined radiation wavelength and thereby high reflectance to modulate the polarized beam. The grating can be optimized for angular bandwidth by controlling the grating's Fourier components either in a single layer or in two grating layers which can also include a termination.

    Abstract: A hybrid package chip and an optical transmitter includes a first sub-chip including a first waveguide and at least one first electrode, and a second sub-chip including a second waveguide and at least one second electrode. The first waveguide is optically coupled to the second waveguide. A first electrode of the first sub-chip and a corresponding second electrode of the second sub-chip are electrically connected to one another by means of a first conductive structure, so as to receive a modulation electrical signal. The first sub-chip is configured to receive external input light and output the light by means of the first waveguide. The at least one first electrode modulates the input light so as to output the modulated light. The second waveguide receives a portion of light from the first sub-chip through coupling.

    Abstract: An optical modulator includes a carrier and a waveguide disposed on the carrier. The waveguide includes a first optical coupling region, a second optical coupling region, first regions, and second regions. The first optical coupling region is doped with first dopants. The second optical coupling region abuts the first optical coupling region and is doped with second dopants. The first dopants and the second dopants are of different conductivity type. The first regions are doped with the first dopants and are arrange adjacent to the first optical coupling region. The first regions have respective increasing doping concentrations as distances of the first regions increase from the first optical coupling region. The second regions are doped with the second dopants and are arranged adjacent to the second optical coupling region. The second regions have respective increasing doping concentrations as distances of the second regions increase from the second optical coupling region.

    Abstract: A plasmonic phase modulator and a method of phase modulation employ modulation of surface plasmons. The plasmonic phase modulator includes a semiconductor substrate configured to provide a surface charge that forms a plasmonic channel at the substrate surface. The modulator further includes an electrode and an insulator between the electrode and the semiconductor substrate. The electrode is configured to provide an electric field that influences the surface charge. The electric field includes a bias field component and a modulation field component. The surface plasmon is supported within the plasmonic channel at an interface between the semiconductor substrate surface and the insulator. A phase of the surface plasmon in the plasmonic channel is modulated by changes in the electric field. The method includes propagating the surface plasmon in the plasmonic channel and varying the modulation field component to modulate the phase of the propagating surface plasmon.
