Appl. No.:

5/918281

Abstract:

A two-part glazing system for use on the lower rails of the upper and lower sashes of a double-hung window. The glazing system comprises a moisture impervious liner member which is snap fit onto the lower rail and underlies the lower edge of the windowpane. A glazing bead is snap fit onto the liner member and extends therefrom to the face of the windowpane. The glazing bead has a gasket for sealing against the windowpane and defining an enclosed drain tank. The gasket prevents substantial amounts of water from reaching the drain tank. Any moisture which does reach the drain tank is drained away through outlet holes in the liner member.

International Classification:

G02B 6/34

Abstract:

A multilayer waveguide coupler comprising a first grating and a second grating is provided. Each first copropagating waveguide of the first grating has a first periodically modulated width. Each second copropagating waveguide of the second grating has a second periodically modulated width. The second grating is positioned so that a phase offset is present between the first periodically modulated width of the first copropagating waveguides and the second periodically modulated width of the second copropagating waveguides. The grating spaced distance and phase offset are selected so that light diffracted out of the first copropagating waveguides and the second copropagating waveguides in the first direction interferes constructively to form the first light beam and light diffracted out of the first copropagating waveguides and the second copropagating waveguides in the second direction interferes destructively.

International Classification:

G02F 1/365

Abstract:

Improved architectures and related methods for enhancing entangled photon generation in optical systems are described. Photons from a light source are coupled from the fundamental mode into an optical resonator in a higher-order mode. The optical resonator comprises a photon generation portion configured to generate entangled photons from the coupled photons. The entangled photons are selectively extracted from the optical resonator in the fundamental mode while the remaining photons propagate through the optical resonator mode and combine with the source photons entering the optical resonator. While the source photons propagating or entering the optical resonator resonate within the optical resonator, the entangled photons are not resonant with the optical resonator, and are selectively extracted before traversing a complete cycle in the optical resonator. Extracted entangled photons can then be output for use in, for example, a communication system.

Abstract:

An optical phased array comprises a first substrate layer, and a first device array on the first substrate layer. The first device array includes a first set of emitters and a first set of waveguides. Each waveguide in the first set of waveguides is respectively coupled to one of the emitters in the first set of emitters.

International Classification:

H01S 3/08
H01S 3/13

Abstract:

An optical phase modulator comprises a cascaded array of optical resonators, wherein each of the optical resonators has an input port and an output port. A plurality of waveguides are coupled between the optical resonators and are configured to provide cascaded optical communication between the optical resonators. Each of the waveguides is respectively coupled between the output port of one optical resonator and the input port of an adjacent optical resonator. A transmission electrode is positioned adjacent to the optical resonators, with the transmission electrode configured to apply a drive voltage across the optical resonators. The optical phase modulator is operative to co-propagate an input optical wave with the drive voltage, such that a resonator-to-resonator optical delay is matched with a resonator-to-resonator electrical delay.
