摘要:
A nano-optic device comprises a plurality of subwavelength apertures in a metal film or between metal islands. The device is adapted to shape a radiation beam transmitted there through. For example, beam shaping includes at least one of beam focusing, beam bending and beam collimating.

A nanostructured optical device includes a metal film or a plurality of metal islands having an array of a plurality of openings having a width that is less than at least one first predetermined wavelength of incident radiation to be provided onto the film or the islands. The metal film or islands are configured such that the incident radiation is resonant with at least one plasmon mode on the metal film or metal islands.

A Fabry-Perot cavity filter includes a first mirror and a second mirror. A gap between the first and the second mirror monotonically varies as a function of width of the filter. This filter may be used with photodetector and a channel selection filter in an optical device, such as a spectrum analyzer. The channel selection filter may be a metal nanooptic filter array which includes plurality of subwavelength apertures in a metal film or between metal islands.

A method of inducing explosive atomization of materials is provided using a metal-oxide-semiconductor (MOS)-based structure under electrical excitation. Explosive atomization of the gate electrode and surrounding dielectric materials creates a microplasma that is substantially confined with the device at the metal/dielectric interface. The device can generate a microplasma in either the accumulation or inversion regime. The high degree of confinement of the microplasma allows chip-scale implementation of atomic emission spectroscopy and detection using a minimal amount of analyte.

A metal nanowire array acts as a band pass filter in the visible to IR range. The filter may be used in a monochromator, spectrometer, color camera, analyte detector or other devices.

摘要:
A vertical dipole array structure includes a substrate that supports a film, which is not comprised of a negative-index metamaterial. The film includes a plurality of tilt-oriented portions and apertures. At least two of the tilt-oriented portions are separated by an aperture, and the tilt-oriented portions are configured such that incident radiation is redirected into a negative or positive refraction direction.
