摘要： According to some embodiments of the present disclosure, an optical device includes a substrate, an optical element, a shifter, and an actuator. The optical element is on the surface of the substrate, and the shifter is adjacent to the optical element such that the optical element is between the substrate and the shifter. Moreover, the actuator is coupled with the shifter, and the actuator is configured to change a space and/or a pressure between the optical element and the shifter. Related methods are also discussed.

摘要： An optical system has a beam-steering device, a light source, and a controller that controls the light source to actively control wavelength of the incoming light to control the output angle of the outgoing light output from the BS device. The BS device may have incoupler, waveguide, and/or outcoupler electrodes, and the system may have corresponding controllable voltage supplies actively controlled by the controller to selectively modify electric fields applied to the BS device to control corresponding operating characteristics of the BS device (e.g., in-plane and/or out-of-plane output angles of the outgoing light and/or device incoupling angle). An alternative optical system has a BS device, a detector array that generates detector signals corresponding to outgoing light received from the BS device, and a controller that processes the detector signals to determine one or more wavelengths of the outgoing light.

摘要： An optical system has a beam-steering device having a planar waveguide region between a tapered incoupler and a tapered outcoupler that respectively define opposing incoupler and outcoupler facets of the BS device. Each region has a substrate, a subcladding layer over the substrate, a core layer over the subcladding, and a top cladding layer over the core. Within the incoupler, at least one of the subcladding and the top cladding has a material having a refractive index that varies with an applied field (e.g., an electric field) applied at the incoupler. The optical system also has a field-applying device that applies the applied field at the incoupler, an output detector that generates a feedback signal based on detected outgoing light output from the outcoupler, and a controller that controls the field-applying device based on the feedback signal to alter the light output from the outcoupler.

摘要： The invention relates to methods for fabricating antireflective surface structures (ARSS) on an optical element using a seed layer of material deposited on the surface of the optical element. The seed layer is removed during or after the etching, and serves to control etching time as well as the transmission region of the optical element having ARSS. Optical elements having ARSS on at least one surface are also provided.

摘要： Methods for producing nanostructured, hydrophobic, superhydrophobic, or hydrophilic, transmissive, anti-reflective surfaces are described. The method for providing a hydrophilic surface includes steps of providing a substrate that is transmissive at at least one wavelength in the infrared to ultraviolet range of the electromagnetic spectrum and comprises at least one surface including nanostructures of a size smaller than the at least one wavelength; and functionalizing the at least one surface with hydroxyl groups thereon. A hydrophobic or superhydrophobic surface can be provided by contacting the at least one surface with a hydrophobic fluoropolymer for a time sufficient to apply at least a monolayer of fluorine-containing material to the at least one surface. These methods provide devices having excellent transmittance and anti-reflectance properties and which are resistant to seawater.

摘要： Systems and methods are provided for a mechanical actuator based on a fiber optic platform. A material that is configured to be activated by light is incorporated into an optical fiber that serves as both an actuator and a power delivery network. This platform is adaptable to different materials, types of motions, and length scales and allows for precise delivery of photons to the material.

摘要： A composition of matter having a coated silicon substrate with multiple alternating layers of polydopamine and polyallylamine bound copper-indium-gallium oxide (CIGO) nanoparticles on the substrate. A related composition of matter having polyallylamine bound to CIGO nanoparticles to form PAH-coated CIGO nanoparticles. A related CIGO thin film made via conversion of layer-by-layer assembled CIGO nanoparticles and polyelectrolytes. CIGO nanoparticles are created via a flame-spray pyrolysis method using metal nitrate precursors, subsequently coated with polyallylamine (PAH), and dispersed in aqueous solution. Multilayer films are assembled by alternately dipping a substrate into a solution of either polydopamine or polystyrenesulfonate and then in the CIGO-PAH dispersion to fabricate CIGO films as thick as 1-2 microns.
