摘要:
An optical-microwave-quantum transducer can include a first nanophotonic slab and a second nanophotonic slab. Each of the first and second nanophotonic slabs can include an optical region and a superconducting region. The first nanophotonic slab can include a pair of torsional beams anchored to a substrate to allow relative rotation between the first and second nanophotonic slabs about an axis of rotation. The optical-microwave-quantum transducer can include a gap between the optical region of the first and second nanophotonic slabs that forms an optical cavity in response to an optical signal, wherein the optical cavity can induce mechanical oscillation of the first nanophotonic slab about the axis of rotation. The mechanical oscillation can induce electrical modulation on a superconducting cavity coupled to the superconducting regions of the first and second nanophotonic slabs.

Optical windows are provided that transmit light such as deep-UV (DUV) light. An exemplary window includes a window substrate that is transmissive to at least one wavelength of the light. The window substrate has an incidence surface decorated with sub-wavelength asperities arranged so as to render the incidence surface solvophobic to the light-transmissive liquid. The arrangement of sub- wavelength asperities can be configured to render the incidence surface super- solvophobic to the liquid. The sub-wavelength asperities can have any of various shapes and combinations thereof, and can be regularly or irregularly arranged.

Methods and apparatus for guidance systems according to various aspects of the present invention operate in conjunction with a projectile including a guidance system having a guidance controller, a detector, and an optical system. The guidance controller controls the path of the projectile according to signals from the detector. The detector generates signals according to an angle of incident energy. The optical system transfers the energy to the detector via a spreader and a condenser. The spreader spreads the incident energy, and the condenser converges the spread energy onto the detector.

摘要:
A light-emitting device, in particular a backlight device, comprises a transparent substrate (2) having a front surface and a rear surface, in which associated to the rear surface are means (3, 4, 5) for generating an electromagnetic radiation that is able to pass through the substrate (2) and come out of the front surface. According to the invention, the device comprises a layer of porous alumina (1) which operates so as to inhibit propagation of said electromagnetic radiation in the directions parallel to the plane of the substrate (2), thus improving the efficiency of extraction of light from the substrate (2) and increasing the directionality of the emitted light.
