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

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.

In one aspect, a multiplexer/demultiplexer system includes an input/output waveguide, two or more output/input waveguides, and a planar, non-periodic, sub-wavelength grating. The grating is configured so that when the system is operated as a multiplexer, each wavelength of light output from one of the two or more output/input waveguides is reflected by the grating toward the input/output waveguide. When the system is operated as a demultiplexer, each wavelength of light output from the input/output waveguide is reflected toward one of the two or more output/input waveguides.

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.

The method includes providing a semiconductor material, providing an etch mask comprising a two-dimensional hole array, and disposing the etch mask on at least one surface of the semiconductor material. The semiconductor material is then etched through the hole array of the etch mask to produce holes in the semiconductor material and thereafter applying a passivation layer to surfaces of the holes. Additionally, the method includes repeating the etching and passivation-layer application to produce a photonic crystal structure that contains ellipsoids within the semiconductor material and annealing the photonic crystal structure to smooth the surfaces of the ellipsoids.
