Abstract:
An integrated device is disclosed which has a substrate and a Rare-Earth Doped Semiconductor layer (REDS layer) integrated with the substrate. The REDS layer is patterned to define one or more optically amplifying structures each having a first I/O port for receiving or outputting a first optical signal, and at least one pump energy receiving port for receiving pumping energy in the form of at least one of electrical pump energy and/or optical pump energy. In one particular set of embodiments, at least one of the optical amplifying structures is a Raman type amplifier where a corresponding pump energy receiving port is structured for receiving Raman type pumping energy having an effective frequency which is about one optical phonon frequency higher than a signal frequency of an optical signal supplied at a corresponding I/O port. Methods are disclosed for fabricating Rare-Earth Doped Semiconductor layers, including providing such layers in semiconductor-on-insulator (SOI) structures and for enhancing the effective, long-term concentrations of incorporated, rare earth atoms. Additionally, non-parallel pumping techniques are disclosed.
Abstract:
Systems and methods for providing a light controlling structure, generally referred to as a microlens or microlens array. For example, in accordance with an embodiment of the present invention, a light controlling structure may be employed to provide a display screen.
Abstract:
A method for manufacturing a light controlling structure, generally referred to as a microlens or microlens array. The method including providing a bundle of optically transparent members; cutting the bundle of optically transparent members to form at least one sheet of optically transparent member segments; and heating the at least one end of the at least one sheet of optically transparent member segments to form lens surfaces thereon.
Abstract:
Systems and methods are provided for a lens or microlens array or non-spherical lens with or without an integrated sensor unit. A dielectric between a substrate and a lens material has curved recesses, which are filled in by the lens material. Light enters the lens material layer and is focused by the curved recess portions.
Abstract:
Systems and methods are disclosed herein to provide zoom lenses. For example, in accordance with an embodiment of the present invention, a zoom lens is provided with a tunable lens. The focal length of the zoom lens may be varied without mechanically moving or changing the separation between one or more lens components.
