    摘要: An apparatus and related methods for spectroscopic analysis of analyte molecules is described. The analyte molecules are disposed near a metallic film that is positioned between a first medium on a first side and a second medium on a second side, the second medium being of higher refractive index than the first medium. A radiation source provides excitation radiation that propagates through the second medium toward the metallic film. The second medium and the metallic film are positioned in evanescent communication with respect to the excitation radiation, and the metallic film comprises lithographically patterned features designed to intensify surface plasmon resonance along the metallic film to promote the emission of Raman radiation from the analyte molecules. A radiation detector detects the Raman radiation emitted from the analyte molecules.

    摘要: A device for deflecting an incident radiation beam through a steering angle to produce a deflected radiation beam is described. The device comprises a photonic crystal receiving the incident radiation beam at a dynamically controlled incidence angle. The photonic crystal is configured to negatively refract the incident radiation beam such that relatively large controlled variations of the steering angle are provided by relatively small controlled variations of the incidence angle.

    摘要: Spin-polarized electrons can be efficiently extracted from an n-doped semiconductor layer (n-S) by forming a modified Schottky contact with a ferromagnetic material (FM) and a δ-doped layer at an interface under forward bias voltage conditions. Due to spin-selection property of the FM-S junction, spin-polarized carriers appear in the n-doped semiconductor layer near the FM-S interface. If a FM-n-n′-p heterostructure is formed, where the n′ region is a narrower gap semiconductor, polarized electrons from the n-S region and holes from the p-S region can diffuse into the n′-S region under the influence of independent voltages applied between the FM and n′ regions and the n′ and p regions. The polarized electrons and holes recombine in the n′-S region and produce polarized light. The polarization can be controlled and modulated by controlling the applied voltages.
