Abstract: Mid-IR supercontinuum laser source in the 3-12 micron region generating at least tens of watts of optical power and based on non-silica optical fiber pumped by a ZBLAN fiber laser generating light at about 2.7 microns. The zero-dispersion wavelength of the non-silica fiber substantially coincides with the lasing wavelength. The proportion of the SC output above 3 microns exceeds 40 percent of the overall power output.

Abstract: A high confinement nonlinear optical fiber is provided along with methods of parametric amplification for use thereof. The nonlinear optical fiber may include a plurality of concentric layers which are configured to provide different guiding regimes to low-frequency and high-frequency components through transverse geometry and refractive index profiling, thus reducing waveguide dispersion. The resulting optical fiber provides a parametric device with phase-matching in any spectral region of interest, such that a fiber optic parametric amplifier (FOPA) implementing the optical fiber can amplify in any spectral window of interest. A narrow-band FOPA configured to minimize phase mismatching is also provided for use with the optical fiber, and may be implemented as a light source or a monochromator.

Abstract: A composite structure having an embedded sensing system is provided, along with corresponding systems and methods for monitoring the health of a composite structure. The composite structure includes composite material and an optical fiber disposed within the composite material. The optical fiber includes a plurality of quantum dots for enhancing its non-linear optical properties. The quantum dots may be disposed in the core, in the cladding and/or on the surface of the optical fiber. The optical fiber is configured to support propagation of the signals and to be sensitive to a defect within the composite material. The quantum dots create a non-linear effect, such as a second order effect, in response to the defect in the composite material. Based upon the detection and analysis of the signals including the non-linear effect created by the quantum dots, a defect within the composite material may be detected.

Abstract: A display device is provided for reflecting a black color, as enabled by an optical splitting photonic liquid crystal waveguide. Sets of top and bottom electrodes are formed in a periodic pattern. A first dielectric layer overlies the set of bottom electrodes, made from a liquid crystal (LC) material with molecules having dipoles responsive to an electric field. A plasmonic layer, including a plurality of discrete plasmonic particles, is interposed between the sets of top and bottom electrodes, and is in contact with the first dielectric layer. A voltage potential is applied between the top and bottom electrodes, generating an electric field. Dipole local orientation and non-orientation regions are created in the liquid crystal molecules in response to the electric field, and a wavelength of light outside the visible spectrum is reflected in response to optical spectrum splitting of the incident light.
