    摘要： An optical metapolarizer device polarizes light while mitigating the absorptive or reflective losses associated with traditional polarizers. The metapolarizer device transmits light of one polarity and rotates the other polarity so that it is closer to the transmitted polarity. As a result, although the light exiting the metapolarizer device is highly polarized, the total transmissivity of the device can be well in excess of 50%, and can approach 100% in the theoretical limit.

    摘要： A multicolor light emitting optical device is a programmable, multifunctional, general-purpose, solid-state light source. The device can use any of several light sources, including LEDs. The device couples a light source and a tunable optical converter composed of a quantum confinement device to produce a tunable, monochromatic light emission. The output wavelength of the optical device can be selected from within a tunable range of the optical (visible, near infrared, or near ultraviolet) spectrum on demand, in real time. The optical device is capable of serving as a tunable light source, a “true color” pixel, and a replacement for bi-color, tri-color, and multi-color light-emitting diodes. The optical device has particular, but not exclusive, application as an indicator light, in room lighting, and as a picture element in video displays.

    摘要： Thermochromic filters are constructed using absorptive, reflective, or fluorescent dyes, molecules, polymers, particles, rods, or other orientation-dependent colorants that have their orientation, order, or director influenced by carrier materials, which are themselves influenced by temperature. These order-influencing carrier materials include thermotropic liquid crystals, which provide orientation to dyes and polymers in a Guest-Host system in the liquid-crystalline state at lower temperatures, but do not provide such order in the isotropic state at higher temperatures. The varying degree to which the absorptive, reflective, or fluorescent particles interact with light in the two states can be exploited to make many varieties of thermochromic filters. Thermochromic filters can control the flow of light and radiant heat through selective reflection, transmission, absorption, and/or re-emission. The filters have particular application in passive or active light-regulating and temperature-regulating films, materials, and devices, and particularly as construction materials and building and vehicle surfaces.

    摘要： The thermally switched reflective optical shutter is a self-regulating “switchable mirror” device that reflects up to 100% of incident radiant energy above a threshold temperature, and reflects up to 50% of incident radiant energy below a threshold temperature. Control over the flow of radiant energy occurs independently of the thermal conductivity or insulating value of the device, and may or may not preserve the image and color properties of incoming visible light. The device can be used as a construction material to efficiently regulate the internal temperature and illumination of buildings, vehicles, and other structures without the need for an external power supply or operator signals. The device has unique aesthetic optical properties that are not found in traditional windows, skylights, stained glass, light fixtures, glass blocks, bricks, or walls. The device can be tailored to transmit sufficient visible light to see through in both the transparent and reflective states, while still providing significant control over the total energy transmission across the device.

    摘要： A thermochromic optical filter incorporating quantum confinement devices is formed as multilayered composite film of semiconducting materials. A quantum well adjacent a barrier layer ensures proper confinement of charge carriers within the well. A transition wavelength (i.e., the energy/wavelength at which the filter becomes transparent) is established by selecting a quantum well material with a bandgap near the desired energy and a barrier layer material with a higher bandgap. For a given reference temperature (e.g., room temperature), the exact transition wavelength is fixed by the thickness of the quantum well. The quantum confinement energy is added to the bandgap energy to yield the transition energy. A thermal control system varies the temperature of the thermochromic filter to adjust the transition wavelength. Temperature changes affect both the bandgap and the quantum confinement energy, and thus the optical properties of the thermochromic filter. The thermochromic filter may function as a longpass filter.

    摘要： A multispectral optical sensor incorporating quantum confinement devices is composed of a solid-state tunable filter, an optional lens, and a photodetector or plurality of photodetectors. The tunable filter is multilayered composite film of semiconducting materials, which includes a quantum well or other quantum confinement structure and barrier materials to ensure the proper confinement of charge carriers within the quantum well. The tunable filter is capable of acting as a long-pass filter. The approximate cut-on wavelength is established through selection of a well material with a bandgap near the desired energy, and barrier materials with a higher bandgap. For a given reference temperature the exact cut-on wavelength may be fixed through careful selection of the dimensions of the quantum confinement structures, whose quantum confinement energy is added to the bandgap energy to yield the cut-on energy. The operational cut-on wavelength at any given moment may be controlled through variation of the temperature of the tunable filter using onboard or external thermal control hardware and through control of an electric field applied across the filter.

    摘要： A thermally switched optical downconverting (TSOD) filter is a self-regulating device including a downconverter that converts incoming light at a variety of wavelengths into longer-wavelength radiation and then directs it using one or more bandblock filters in either the inward or outward direction, depending on the temperature of the device. This control over the flow of radiant energy occurs independently of the thermal conductivity or insulating properties of the device and may or may not preserve the image and color properties of incoming visible light. The TSOD filter is energy-efficient as it can be used to regulate the internal temperature and illumination of buildings, vehicles, and other structures without the need for an external power supply or operator signals. The TSOD filter has unique aesthetic and optical properties not found in traditional windows, skylights, stained glass, light fixtures, glass blocks, bricks, or walls.
