    Abstract: Embodiments of the present invention are directed to beamsplitters that include optical elements to correct for beam offset. In one embodiment, a beamsplitter includes a first plate having two approximately parallel and opposing planar surfaces and a partially reflective layer coating one of the planar surfaces, and a compensator plate having two approximately parallel and opposing planar surfaces. The compensator plate is positioned so that an incident beam of light passing through the compensator plate acquires a first beam offset. Subsequently, the incident beam of light with the first beam offset passing through the first plate is split into a reflected beam and a transmitted beam by the partially reflective layer where the transmitted beam has a second beam offset that substantially cancels the first beam offset such that the transmitted beam is approximately parallel to and aligned with the incident beam.

    Abstract: Embodiments of the present invention are directed to photovoltaic cells that include a surface relief grating to couple out-of-plane light into the leaky slab modes of the photovoltaic cells. In one embodiment of the present invention, a photovoltaic cell comprises a bottom electrode, a light-absorption layer disposed on the bottom electrode, and a top electrode disposed on the light-absorption layer. The top electrode is configured with a grating that enables light incident on the grating to be scattered into the light-absorption layer and traps incident light with particular polarizations and incident angles in the grating to interact with the light-absorption layer.

    Abstract: A system and methods for dividing an optical beam in a hollow metallized waveguide are disclosed. The method includes directing an optical signal into a first section of a hollow metallized waveguide. The optical signal is adiabatically expanded in a second section of the hollow metallized waveguide coupled to the first section. The optical signal is split with an in-plane optical beam splitter located in a third section of the hollow metallized waveguide coupled to the second section.

    Abstract: A computer system has an optical data distributing device for transmitting and distributing optical signals. A laser source generates light for forming the optical signals, and an optical fiber with a graded index of refraction couples the light from the laser source to the optical data distributing device. A lens is disposed to image light generated by the laser source into an input end of the optical fiber. The magnification of the lens is selected as a function of a ratio of a numerical aperture and diameter of the laser source divided by a ratio of a numerical aperture and diameter of the optical fiber.

    Abstract: An optical resonator configured to be tuned using piezoelectric actuation, includes a core, the core being configured to transmit light; a piezoelectric layer; a first electrode and a second electrode. The piezoelectric layer is interposed between the first electrode and the second electrode. A voltage difference across the first and second electrodes alters a geometric dimension of the piezoelectric layer such that physical force is applied to the core and a resonant optical frequency of the resonator is changed. A method of utilizing mechanical stress to tune an optical resonator includes applying physical force to the resonator by subjecting a piezoelectric material to an electric field, the physical force changing a resonant frequency of the resonator.
