摘要： An optical modulator and related methods are described. In accordance with one embodiment, the optical modulator comprises a horizontal waveguide grating structure (WGS) receiving an incident radiation beam propagating in a non-horizontal direction. The WGS includes a horizontal waveguiding layer along which a lateral propagation mode is guided, the lateral propagation mode having a vertically extending mode profile. The optical modulator further comprises a multiple quantum well (MQW) layer sufficiently proximal to the horizontal waveguiding layer to be within a vertical extent of the mode profile of the lateral propagation mode. The optical modulator further comprises an electric field source applying a time-varying electric field to the MQW layer. The optical modulator modulates the incident radiation beam according to the time-varying electric field to generate a modulated radiation beam propagating in one of a transmitted direction and a reflected direction.

摘要： Embodiments of the invention provide a method and an apparatus for performing self-aligned, sub-wavelength optical lithography. One embodiment provides a region of photoresist above a conductive surface having a plurality of periodically arrayed openings extending therethrough. At least a portion of the region of photoresist is then exposed to a light, wherein the intensity of the light is less than the intensity required to cure the photoresist. In so doing, at least one self-aligned, sub-wavelength location in at least one location of the region of photoresist is cured.

摘要： A nanowire light emitting diode (LED) and method of emitting light employ a plasmonic mode. The nanowire LED includes a nanowire having a semiconductor junction, a shell layer coaxially surrounding the nanowire, and an insulating layer, which is plasmonically thin, isolating the shell layer from the nanowire. The shell layer supports a surface plasmon that couples to the semiconductor junction by an evanescent field. Light is generated in a vicinity of the semiconductor junction and the surface plasmon is coupled to the semiconductor junction during light generation. The coupling enhances one or both of an efficiency of light emission and a light emission rate of the LED. A method of making the nanowire LED includes forming the nanowire, providing the insulating layer on the surface of the nanowire, and forming the shell layer on the insulating layer in the vicinity of the semiconductor junction.
