摘要： Controlling the propagation of electromagnetic radiation is described. A photonic bandgap medium is placed in the path of the electromagnetic radiation, the photonic bandgap medium comprising a photorefractive material. Control radiation is projected onto a surface of the photonic bandgap medium. The control radiation spatially varies a refractive index of the photorefractive material to control propagation of the electromagnetic radiation through the photonic bandgap medium.

摘要： A reconfigurable surface enhanced Raman spectroscopy (SERS) apparatus, system and method employ a stimulus responsive material to move nanorods of a plurality between inactive and active configurations. The apparatus includes the plurality of nanorods and the stimulus responsive material. The system further includes a Raman signal detector. The method of reconfigurable SERS includes providing the plurality of nanorods and exposing the stimulus responsive material to a stimulus. The exposure causes a change in one or more of a size, a shape and a volume of the stimulus responsive material that moves the nanorods between the inactive and active configurations. The active configuration facilitates one or both of production and detection of a Raman scattering signal emitted by the analyte.

摘要： Raman spectroscopy systems include an analyte, a radiation source configured to emit incident radiation having a wavelength, and a detector that is capable of detecting only radiation having wavelengths within a detectable range that includes at least one wavelength corresponding to hyper Raman scattered radiation scattered by the analyte. The wavelength of the incident radiation is outside the detectable range. In particular systems, all wavelengths of radiation that are scattered in the direction of the detector impinge on the detector. Raman spectroscopy methods include providing an analyte and irradiating the analyte with incident radiation having a wavelength, providing a detector capable of detecting only wavelengths of radiation within a detectable range that does not include the wavelength of the incident radiation, and detecting Raman scattered radiation scattered by the analyte. A continuous path free of radiation filters may be provided between the analyte and the detector.
