In one embodiment, a method for selectively amplifying and/or filtering frequency bands is disclosed and includes providing a light source of an first wavelength, selecting an output comprising at least a second wavelength, the second wavelength differing from the first wavelength, calculating a domain architecture for a nonlinear optical material configured to output the second wavelength from an input of the first wavelength, aperdiocially poling the nonlinear optical material to create an aperiodic nonlinear optical material having the calculated domain architecture, irradiating the aperiodic nonlinear optical material with the first wavelength from the light source, and outputing the second wavelength from the aperiodic nonlinear optical material.

Abstract: The present application is directed to high speed optical system. In one embodiment, the optical system includes a photodiode which is sensitive to a wavelength of light, a first source of photons at a first wavelength to which the photodiode is sensitive incident on the photodiode, a second source of photons at a second wavelength to which the photodiode is insensitive incident on the photodiode, an electric field across the photodiode in excess of the breakdown voltage thereof and configured to result in an avalanching of electrons in the photodiode when the photons from the first source strike the photodiode, and a capture device in optical communication with and configured to capture light reflected from the photodiode. The avalanche of electrons within the photodiode results in a photorefractive response which changes the index of refraction in the photodiode. Light reflected from the photodiode is modulated by the photorefractive response and is subsequently captured by the capture device.

Abstract: A method is provided for initiating and sustaining a combustive reaction in a solid fuel. The method includes generating at least one pulsed optical signal and directing the pulsed optical signal to a plurality of ignition points within at least one combustion chamber containing a solid fuel. The pulsed optical signal is generated by an optical source, e.g. a laser pump, and modulated using an intensity profiler. The intensity profiler modulates the pulsed optical signal to initially have a first peak power sufficient to initiate a combustive reaction in a solid fuel. The intensity profiler further modulates the pulsed optical signal to subsequently have a second peak power sufficient to sustain the combustive reaction until sufficient exothermic energy is released by the combustive reaction to make the reaction self-sustaining.

Abstract: A diode laser for providing a high-energy coherent light beam suitably includes an array of laser diodes, each producing a laser beamlet. The beamlets are provided to a spatial light modulator (SLM) with an array of pixels, each pixel corresponding to a portion of the light beam. The phase variation across the light beam wavefront is monitored at a detector, and a feedback signal indicative of the phase variation is provided to control electronics. The control electronics process the feedback signal to modulate a local index of refraction within one or more pixels of the SLM to reduce the variation in phase across the beam wavefront. Because phase variations across the beam wavefront are reduced, relatively large diode arrays can be formulated, thereby resulting in relatively high powered diode lasers.

Abstract: A first control optics assembly receives an incoming optical image. A template optical element produces a template optical intensity profile. A second control optics assembly receives the template optical intensity profile. A polarization separator receives an output from the second control optics. A quarter wave plate changes the polarization of the polarized output therefrom. A combiner receives an output from the first control optics assembly and an output from the quarter wave plate and provides a combined, co-linear propagation output image having an initial beam size. An SLM provides absorption of a portion of the combined output image which changes the local index of refraction of the SLM so that the local reflection at the template optical intensity profile changes.

Abstract: An integrated circuit formed on a substrate suitably includes a number of superconducting junctions. Each superconducting junction includes a first superconducting material disposed upon the substrate, an insulating material formed on the first superconducting material, and a second superconducting material formed on the insulating material to create a Josephson junction. The second superconducting material is a different material from the first superconducting material to aid in manufacturability. Any number of electrically conductive interconnects are also provided to interlink the superconducting junctions to thereby form the integrated circuit. Examples of superconducting materials that may be used for the various layers include YBaCu3O7-y (YBCO) and Bi2Sr2CaCu2Oy (Bi2212). Various circuits and techniques relating to superconducting devices are also described.

Abstract: An active optical system and method for phase-shifting desired portions of an incoming optical wavefront. A control optics assembly receives an incoming optical wavefront and adjusts that incoming optical wavefront in accordance with first desired wavelength and beam propagation parameters. Spatial light modulator (SLM) addressing optics receives the control optics output wavefront and produces a desired beam size therefrom. An SLM receives the output from the SLM addressing optics and provides localized phased shifting of the resulting wavefront. The SLM comprises a microscopic array of pixelated silicon nanocluster elements and a voltage source for applying independently controlled voltages on desired nanocluster elements. SLM egressing optics receives the output of the SLM and returns the beam size of the wavefront to the initial beam size. The output of the SLM egressing element has desired portions of its phase shifted relative to the incoming optical wavefront.

Abstract: A method of forming a fingerprint-resistant anti-reflection coating for plastic substrates that includes an upper thin film layer to be exposed to an ambient environment. The upper layer has an optical path length of about a quarter wave at a pre-selected design wavelength. A lower thin film layer interfaces a plastic substrate. The lower layer has an index of refraction greater than an index of refraction of the upper layer. The lower layer has an optical path length of about a half wave at the pre-selected design wavelength. The reflectance of light from the fingerprint-resistant two-layer anti-reflection coating when applied to plastic substrates is substantially the same in oil and the ambient environment.

The upper layer has an optical path length equal to a quarter wave at a pre-selected design wavelength in the range of about 450 to 550 nanometers. A lower thin film layer interfaces a plastic substrate. The lower layer has an index of refraction greater than an index of refraction of the upper layer. The index of refraction of the lower layer is at least 0.5 higher than the index of refraction of said upper layer and has an optical path length equal to a half wave at the pre-selected design wavelength in the range of about 450 to 550 nanometers. The reflectance of light from the fingerprint-resistant two-layer anti-reflection coating when applied to plastic substrates is essentially the same in oil and the ambient environment.

Abstract: A system that accepts and stores raw time and expense data for a plurality of businesses—each business defining a separate account that is accessible and usable by authorized users for the particular business. The inventive system automatically converts the raw time and expense data by considering any client or project-specific billing requirements (e.g., flat-fee, maximum fee, discount, write-offs, etc.) and by applying such specific requirements to the raw time and/or expense data in generating an invoice. The raw data may be referred to as internal data in that it is used only by the business providing a service to their client, and in connection with that business's account by the inventive system. A client will not have access to internal data. The invoice data, on the other hand, may be referred to as external data because it is communicated to the client and also used in connection with that business's account.
