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.

摘要： An electromagnetic resonance device includes an input reflector, an output reflector, and a negative index material (NIM) disposed between the input reflector and the output reflector. The input reflector and output reflector are configured to be reflective to radiation having a wavelength of interest. The NIM is configured to have a negative refraction at the wavelength of interest. A first radiation is reflected by the input reflector toward the first surface of the NIM, passes through the NIM, and is focused on the output reflector as a second radiation. The second radiation is reflected by the output reflector toward the second surface of the NIM, passes through the NIM, and is focused on the input reflector as the first radiation. A gain medium may be included to amplify the first radiation and the second radiation to generate a laser radiation.

摘要： A nano-colonnade structure-and methods of fabrication and interconnection thereof utilize a nanowire column grown nearly vertically from a (111) horizontal surface of a semiconductor layer to another horizontal surface of another layer to connect the layers. The nano-colonnade structure includes a first layer having the (111) horizontal surface; a second layer having the other horizontal surface; an insulator support between the first layer and the second layer that separates the first layer from the second layer. A portion of the second layer overhangs the insulator support, such that the horizontal surface of the overhanging portion is spaced from and faces the (111) horizontal surface of the first layer. The structure further includes a nanowire column extending nearly vertically from the (111) horizontal surface to the facing horizontal surface, such that the nanowire column connects the first layer to the second layer.
