    • The present invention is a Raman laser and methods related thereto. In the preferred embodiments, the Raman laser comprises a laser pump signal in a fiber waveguide which is optically coupled to a micro-resonator through a fiber taper. The micro-resonator is constructed from a material that has a high Q when it is formed into a micro-resonator and is phase matched to the waveguide. The lasing frequency can be determined based upon the pump input or the micro-resonator material. In the preferred embodiments, the micro-resonator is constructed from a fused silica material. The present invention provides a compact laser with improved emissions and coupling efficiencies and the ability to use stimulated Raman scattering effects to create lasers having frequencies that are otherwise difficult to obtain. Alternative configurations include multiple micro-resonators on a single fiber waveguide and/or utilizing multiple waveguides attached to one or more micro-resonators. The Raman laser can be made to operate in a continuous-wave as opposed to self-pulsing mode.

    • A method for fabricating a nanometer slot waveguide comprises applying a spacer layer to a first waveguide structure, wherein the first waveguide structure includes a waveguide layer and a substrate layer and the waveguide layer has a refractive index greater than the substrate layer. A second waveguide structure is applied to the spacer layer, wherein the second waveguide structure includes a waveguide layer and a substrate layer, and the waveguide layer has a refractive index greater than the substrate layer. The substrate layer of the second waveguide structure is removed to create an intermediate waveguide structure and portions of the intermediate waveguide structure are removed to create a nanometer slot waveguide structure.

    • Various embodiments of the present invention are directed to compact systems for generating polarization-entangled photons. In one embodiment of the present invention, a non-degenerate, polarization-entangled photon source comprises a half-wave plate that outputs both a first pump beam and a second pump beam, and a first beam displacer that directs the first pump beam into a first transmission channel and the second pump beam into a second transmission channel. A down-conversion device converts the first pump beam into first signal and idler photons and converts the second pump beam into second signal and idler photons. A second beam displacer directs both the first signal and idler photons and the second signal and idler photons into a single transmission channel. A dichroic mirror directs the first and second signal photons to a first fiber optic coupler and the first and second idler photons to a second fiber optic coupler.
