摘要： A method for manufacturing a thin film solar cell involves applying an inductively-coupled-plasma during the deposition of selenium. A precursor thin film is formed. The precursor thin film can include copper, indium, and gallium. The inductively-coupled-plasma is applied to the selenium as the selenium is deposited into the precursor thin film to produce the thin film. The selenium is deposited into precursor thin film by evaporation, sputtering, or using a reactive gas. An inert gas is used as a carry and discharge gas. The precursor thin film and the selenium are deposited using a deposition system. The deposition system includes an inductively-coupled-plasma device. The inductively-coupled-plasma device includes a quartz plate, a plasma discharge coil, and an inlet system. The deposition can be an in-line system, a roll-to-roll system, or a hybrid system.

摘要： A method and system for providing a splitter/combiner is disclosed. The splitter/combiner includes a first birefringent wedge having a first optic axis and a first wedge angle and a second birefringent wedge having a second optic axis and a second wedge angle. The second birefringent wedge is optically coupled with the first birefringent wedge. The second wedge angle is complementary to the first wedge angle. The second optic axis is perpendicular to the first optic axis such that an extraordinary signal for the first birefringent wedge is an ordinary signal for the second birefringent wedge. The first and second birefringent wedges establish a first path for a first portion of a first optical signal and establish a second path for a second portion of the first optical signal. The first path and the second path are separated by an angle. The first optical signal travels from the first birefringent wedge to the second birefringent wedge. The first birefringent wedge and the second birefringent wedge also combine a second optical signal travelling along the first path with a third optical signal travelling along the second path. The second optical signal and the third optical signal travel from the second birefringent wedge to the first birefringent wedge.

摘要： A method and system for providing an optical circulator is disclosed. The optical circulator includes a first port, a second port, a third port, and means for establishing a first optical path and a second optical path. The first optical path is from the first port to the second port. The second optical path is from the second port to the third port. The optical path establishing means also includes a wedge and a first birefringent material. The wedge intersects the second optical path but not the first optical path. The wedge is for ensuring that the second optical path includes the third port but not the first port. The wedge does so by deflecting an optical signal input from the second port, but not an optical signal from the first port. The first birefringent material intersects the first optical path and the second optical path and is disposed between the wedge and the second port along the second optical path. The first birefringent material is for ensuring that the second optical path includes the third port but not the first port and for ensuring that the first optical path includes the second port.

摘要： The present invention provides a line of optical interleavers in which a novel beam-swapping element is utilized. The beam-swapping element of the present invention provides an effective and inexpensive alternative to polarization rotators and birefrigent elements employed in the prior art optical interleavers, hence rendering a simple and low-cost assembly to the optical interleavers of the present invention. The optical interleavers of the present invention further advantageously exploit a combination of two wavelength filters to cancel out wavelength-filter-induced-dispersion. Efforts are also painstakingly made in the optical interleavers of the present invention to substantially minimize other dispersion effects. As such, the optical interleavers of the present invention constitute the first kind in the art in which various dispersion effects are substantially minimized. Such characteristics would be highly desirable in fiber-optic networks. The optical interleavers of the present invention can be advantageously configured as multiplexers, de-multiplexers, or routers.
