International Classification:

H01S 300

US Classification:

359334, 359134, 35934131

Abstract:

Optical systems of the present invention include a plurality of optical processing nodes in optical communication via at least one signal varying device. The signal varying devices includes an optical fiber suitable for facilitating Raman scattering/gain in a signal wavelength range and a pump energy source for providing pump energy in a plurality of pump wavelengths. The pump source provides sufficient pump energy in each pump wavelength to stimulate Raman scattering/gain in the optical fiber within the signal wavelength range. The pump wavelengths are selected such that the combined Raman gain resulting from the pump energy supplied by each pump wavelength produces a desired signal variation profile in the signal wavelength range. In addition, the pump energy supplied by at least one of the pump wavelengths can be varied to produce a controlled signal intensity variation profile over the signal wavelength range in the optical fiber.

Inventors:

Ruxiang Jin - Duluth GA, US

International Classification:

H02J 3/38
H02J 50/30
H02J 7/35

Abstract:

A dynamic network for energy-distribution can comprise energy converters, communication-and-control modules, power distribution switches, energy storage batteries, light emitters and light receivers located at spatially separated sites connected by optical transmission media, wherein each site can be equipped with energy transmitting, receiving or storage functionalities as well as signal-communication functionalities. The topology of the energy-distribution network can be changed dynamically by activating or deactivating optical links among the sites via software control. Charging vehicles can act as moving sites to remotely deliver energy to or receive energy from devices located at different sites of a network.

Appl. No.:

13/887327

Inventors:

Ruxiang Jin - Duluth GA, US

International Classification:

H01L 31/052
F21V 8/00
F24J 2/10

US Classification:

136246, 126684, 362551

Abstract:

A reflective concentrating optical apparatus capable of efficient solar power collection and conversion is disclosed. A corrugated monolithic reflector or a modified Mersenne optical system with corrugated primary reflector concentrates sunlight with high irradiance uniformity and minimal optical loss, so that an optical fiber bundle or a high efficiency solar cell can be placed near the focal area for efficient light collection or solar-to-electrical power conversion. The solar cell is directly attached onto a phase-transition cooling apparatus comprising a heat pipe and a heat sink to keep the solar cell within a temperature range that enables high solar-to-electrical power conversion efficiency.
