An integrated laminate structure adapted for application in the context of solar technology, wafer technology, cooling channels, greenhouse illumination, window illumination, street lighting, traffic lighting, traffic reflectors or security films, includes a first carrier element such as a piece of plastic or glass, optionally having optically substantially transparent material enabling light transmission therethrough, a second carrier element provided with at least one surface relief pattern including a number of surface relief forms and having at least one predetermined optical function relative to incident light, the second carrier element optionally including optically substantially transparent material enabling light transmission therethrough, the first and second carrier elements being laminated together such that the at least one surface relief pattern has been embedded within the established laminate structure and a number of related cavities have been formed at the interface of the first and second carrier elements. An applicable method of manufacture is presented.

A method for fabricating one or more elements in a multi-lens column. Drops of ultraviolet (UV)-curable liquid are dispensed by an inkjet on a substrate, which may be supported by a chuck. A non-uniform liquid film is then formed, such as by spreading and merging of the inkjetted drops. The film is then locally heated, such as by using a digital micromirror device array. The film is then cured by exposing it to UV light, where the cured film together with the substrate form an element of the multi-lens column. The substrate is then brought to a metrology station where optical metrology is performed on the cured film and the substrate for quality control.

The invention relates to a method for producing embedded hydrogel contact lenses each having a magnetized insert that comprises magnetic particles and is centrally embedded in the bulk hydrogel material of the embedded hydrogel contact lens. During molding, a magnetized insert can be centered and held in position in a lens mold by using a magnet placed below the lens mold. The invention also relates to an embedded hydrogel contact lens produced from a method of the invention.

Systems and methods are described herein for an optical beam-steering device that includes an optical transmitter and/or receiver to transmit and/or receive optical radiation from an optically reflective surface. An array of adjustable dielectric resonator elements is arranged on the surface with inter-element spacings less than an optical operating wavelength. A controller applies a pattern of voltage differentials to the adjustable dielectric resonator elements. The pattern of voltage differentials corresponds to a sub-wavelength reflection phase pattern for reflecting the optical electromagnetic radiation. One embodiment of a dielectric resonator element includes first and second dielectric members extending from the surface. The dielectric resonator elements are spaced from one another to form a gap or channel therebetween. A voltage-controlled adjustable refractive index material is disposed within the gap.

Embodiments include a LIDAR scanning system. A laser is configured to emit pulses of light. A transmit reconfigurable-metasurface is configured to reflect an incident pulse of light as an illumination beam pointing at a field of view. This pointing is responsive to a first holographic beam steering pattern implemented in the transmit reconfigurable-metasurface. A receive reconfigurable-metasurface is configured to reflect a return of the illumination beam to an optical detector. This pointing is responsive to a second holographic beam steering pattern implemented in the receiving reconfigurable-metasurface. An optical detector includes an array of detector pixels. Each detector pixel includes (i) a photodetector configured to detect light in the return of the illumination beam and (ii) a timing circuit configured to determine a time of flight of the detected light. The optical detector is also configured to output a detection signal indicative of the detected light and the time of flight.
