Abstract: An optical monitoring arrangement utilizes the properties of a blazed Bragg grating to redirect a portion of an optical signal out of the axial path and into a detecting device. A plurality of blazed Bragg gratings are utilized, each having unique properties, to increase the robustness of the monitor. In particular, by utilizing a plurality of N gratings, the bandwidth of the monitor may be increased N-fold (assuming no overlap in wavelength between gratings). Alternatively, an improvement in resolution can be obtained by utilizing a narrower bandwidth and measuring N times the number of raw data points within that bandwidth. A combination of increase in bandwidth and resolution may be obtained by a comprise between these two extremes. Chirped blazed gratings may also be employed.

Abstract: A beam splitting element having a diffraction grating is designed by careful selection of device parameters such as grating period, duty cycle, depth and refractive index. In particular, the parameters are selected in such a way that the product of refractive index, depth and duty cycle is equal to or bigger than a predetermined value. The diffraction grating device designed by these rules exhibits a high diffraction efficiency and small polarization dependence.

Abstract: A spectroscopic apparatus which is compact in size and performs high-precision light-splitting with a large angular dispersion. An optical input-processing section outputs a filtered transmitted light, using a bandpass filter that transmits only wavelength bands at one period of an input light, and collects the filtered transmitted light to generate a collected beam. An optic includes a first reflection surface and a second reflection surface which are high but asymmetric in reflectivity, and causes the collected beam incident thereon to undergo multiple reflections within an inner region between the first reflection surface and the second reflection surface, to thereby cause split beams to be emitted via the second reflection surface. A received light-processing section performs received light processing of the beams emitted from the optic. A control section variably controls at least one of a filter characteristic of the bandpass filter and an optical length through the optic.

Abstract: Encoded spatio-spectral information processing is performed using a system having a radiation source, wavelength dispersion device and two-dimensional switching array, such as digital micro-mirror array (DMA). In one aspect, spectral components from a sample are dispersed in space and modulated separately by the switching array, each element of which may operate according to a predetermined encoding pattern. The encoded spectral components can then be detected and analyzed. In a different aspect, the switching array can be used to provide a controllable radiation source for illuminating a sample with radiation patterns that have predetermined characteristics and separately encoded components. Various applications are disclosed.

Abstract: Optical devices and related methods are provided. One example of the optical device includes two or more optical members joined together to form a stack. Each of the optical members in the stack includes a reflecting surface that has a corresponding slope, where the slope of each reflecting surface is different. In addition, disposed on each reflecting surface is a material that is reflective for a particular wavelength of light, so that each optical member reflects a different wavelength, and so that the optical members in the stack are able to collectively image the reflected signals onto a two dimensional detection plane.
