摘要： Embodiments of the present invention are directed to systems for performing surface-enhanced Raman spectroscopy. In one embodiment, a system (100, 400, 600, 800, 900, 950) for performing Raman spectroscopy comprises a substrate (102) substantially transparent to a range of wavelengths of electromagnetic radiation and a plurality of nanowires (104, 602) disposed on a surface of the substrate. The nanowires are substantially transparent to the range of wavelengths of electromagnetic radiation. The system includes a material disposed on each of the nanowires. The electromagnetic radiation is transmitted within the substrate, into the nanowires, and emitted from the ends of the nanowires to produce enhanced Raman scattered light from molecules located on or in proximity to the material.

摘要： A system includes a non-uniform grating (100) having a first region (110) with a first refractive index and second regions (120) with a second refractive index. A pattern of the second regions (120) varies with an angular coordinate such that phase shifts of an incident beam (130) created by the grating (100) cause destructive interference that creates an intensity minimum within an output beam (134) from the grating (100).

摘要： A hybrid guided-mode resonance (GMR) grating, an optical filter and a method of optical filtering employ distributed Bragg reflection. The hybrid GMR grating includes a waveguide layer that supports a GMR having a GMR resonant frequency. The hybrid GMR grating further includes a diffraction grating that couples a portion of a signal incident on the hybrid GMR grating into the waveguide layer; and a distributed Bragg reflector (DBR) that reflects another portion of the incident signal. The coupled portion of the incident signal has a frequency corresponding to the GMR resonant frequency. The reflected portion has a frequency away from the GMR resonant frequency. The optical filter includes the hybrid GMR grating and a coupler. The method includes coupling an optical signal into the hybrid GMR grating and further coupling a reflected signal out of the hybrid GMR grating.

摘要： Liquid crystal coupled light modulation includes a light guide to guide light by total internal reflection (TIR), a diffraction grating and a liquid crystal sandwiched between the diffraction grating and the light guide. The liquid crystal has a state with a first refractive index to defeat TIR and another state with a second refractive to facilitate TIR at a surface of the light guide. The liquid crystal in the first refractive index state is to couple out a portion of the guided light to the diffraction grating and the diffraction grating is to provide diffractive redirection of the coupled portion out of the light modulator.
