Appl. No.:

11/919836

Inventors:

Michael W. Haney - Oak Hill VA, US
Michael J. McFadden - San Antonio TX, US

International Classification:

H01L 31/00

US Classification:

136259

Abstract:

The present invention is an apparatus and method for the realization of a photovoltaic solar cell that is able to achieve greater than 50% efficiency and can be manufactured at low cost on a large scale. The apparatus of the present invention is an integrated optical and solar cell design that allows a much broader choice of materials, enabling high efficiency, the removal of many existing cost drivers, and the inclusion of multiple other innovations.

Filed:

Jun 21, 1999

Appl. No.:

9/337353

Inventors:

Marc P. Christensen - Ashburn VA
Predrag Milojkovic - Bethesda MD
Michael W. Haney - Herndon VA

Assignee:

Applied Photonics, Inc. - Fairfax VA

International Classification:

G02B 632

US Classification:

2502011

Abstract:

An optical interconnection for connecting a first integrated circuit to a second integrated circuit includes a plurality of light sources, a plurality of light detectors, a symmetric imaging system, and a plurality of beam steering elements, one for each of the plurality of light sources. Each of the beam steering elements is configured to steer light from its corresponding light source to a new angle which causes the symmetric imaging system to have an effective aperture closer to its plane of symmetry. A mirror may be inserted in the plane of symmetry of the imaging system that folds the system back upon itself, making the object plane and image plane co-incident.

Appl. No.:

8/378015

Inventors:

Michael W. Haney - Herndon VA
Marc P. Christensen - Ashburn VA

Assignee:

Capital Photonics, Inc. - Washington DC

International Classification:

H04J 1400

US Classification:

359117

Abstract:

A sliding banyan switching network is disclosed for signal switching in an electrical or an optical network. The sliding banyan network routes up to N signals through a plurality of stages, each containing a plurality of switches. The sliding banyan network determines when a signal reaches its destination address by keeping track of the number of successful consecutive routings through the stages of the network. When this number reaches a predetermined number, the signal has reached its destination. The nodes of each stage are formed on a single substrate and the interconnections are implemented by optical connections. Only a single input line and a single output line for each set of nodes connects the sliding banyan network to the external system.

Abstract:

Dispersive optical systems and methods are disclosed, as well as energy generation systems utilizing such systems in combination with photovoltaic cells. A dispersive optical system includes an optical element, a layer of high-dispersion microprisms, and a layer of low-dispersion microprisms. The optical element is configured to focus a light beam. The layer of high-dispersion microprisms is configured to refract the light beam. The layer of low-dispersion microprisms is configured to refract the light beam. The dispersive optical system is configured to optically concentrate and disperse input light incident thereupon into an output comprising a plurality of bands of light each having a different wavelength. A method of optical dispersion includes focusing a light beam with an optical element, refracting the light beam with a layer of high-dispersion microprisms, and refracting the light beam with a layer of low-dispersion microprisms.
