Abstract: A Raman spectroscopy system is disclosed which includes a sub-wavelength resonant grating filter and a photodiode with integrated sub-wavelength resonant grating filter are disclosed. The resonant grating filter comprises an array of diffraction elements having a periodic spacing that is less than the wavelength of radiation to be filtered and which are formed over a waveguide layer. The filter, which can reject a specific wavelength of radiation, can be placed between a Raman sample and a Raman detector in order to filter radiation that is elastically scattered from the sample while transmitting other wavelengths. The wavelength rejected by the filter can be selected by tilting the filter with respect to the radiation incident upon the filter.

Abstract: A light amount is increased and an analyzing accuracy can be kept in accordance with an enlargement of a load angle, however, a scattered light tends to be loaded in an analysis accompanying the scattered light and a dynamic range of a concentration which can be measured becomes narrow. A light is dispersed by a light dispersing portion, a load angle of the received light is changed per wavelength, the load angle is made larger in the light of a wavelength having a small light amount, and the load angle is made smaller in the light a wavelength having a large light amount and used for an analysis accompanying a scattered light. Accordingly, it is possible to gain a dynamic range of a concentration which can be measured in the analysis accompanying the scattered light, while increasing the light amount and maintaining the analyzing accuracy.

Abstract: A property of a fluid is determined spectroscopically, such as for the purposes of in vivo blood analysis. First the position of a volume of interest through which the fluid flows is determined by an optical detection step by making use of an objective. Preferably the optical detection step is an imaging step. Next the objective is moved to bring the focal point of the objective into coincidence with the volume of interest. In this position an optical spectroscopic step is performed. This has the advantage that the measurement beam for performing the optical spectroscopy travels along the optical axis for optimum efficiency.

Abstract: Method and material for spectroscopic detection of organic chemicals. The material is a substantially optically transparent solid, such as ZnS, having a high surface area for adsorption of an analyte, such as organic chemical vapors. The solid material preferably has metal nanoparticles, such as gold, silver or copper nanoparticles, deposited on the surface for signal enhancement. A template compound, such as cetyl trimethyl ammonium bromide and alkoxylate block polymers, may be used during the material synthesis, such as reacting zinc chloride and sodium sulfide in the presence of the template compound, and later removed through calcination and washing to achieve the high surface area. The method of use includes collecting an analyte on the material and detecting the spectroscopic response of the analyte while it is collected on the surface. The mechanism of collection may include adsorbing, absorbing, and preconcentrating. Preferably, the spectroscopic response is selected from infrared spectra or ultraviolet-visible spectra.

Abstract: The invention relates to a method and apparatus for detecting defects in a semiconductor or silicon structure at room temperature, and in an efficient time, using photoluminescence. The invention employs the use of a high intensity beam of light preferably having a spot size between 0.1 mm 0.5 microns and a peak or average power density of 104-109 w/cm2 with a view to generating a high concentration of charge carriers, which charge characters detect defects in a semiconductor by interacting with same. These defects are visible by producing a photoluminescence image of the semiconductor. Several wavelengths may be selected to identify defects at a selective depth as well as confocal optics may be used.
