A novel approach, called pigtailing, is presented for the construction of optical detectors for capillary electrophoresis. Optical components and procedures from other fields, mainly telecommunications, are incorporated into these devices to give miniaturi ...
We have designed and developed a new class of optical fiber components based on thin-film coatings and fiber gratings. In our design, the function of the thin-film fiber coating is to provide an electrical means to regulate the optical response of the fibe ...
We present a tunable interference filter for infrared and visible light that scans the desired part of the optical spectrum within milliseconds. A single pixel detector measures serially the intensity at selected wavelengths. This concept avoids expensive ...

We develop a pseudospectral multi-domain formulation for the accurate modeling of generic diffractive optical elements, here exemplified by off-plane waveguide holograms for the coupling between guided waves and freely propagating wavefronts. The individua ...

We present a general 3-D spectral collocation method for the analysis of diffractive optical elements (DOEs). The method computes a direct solution to the Maxwell's equations in the time domain. The computational domain is decomposed into a number of small ...
We report on the investigation of refractive microlens arrays with diffractive grating surfaces in the context of a microspectrometer array system. The elements fabricated combine the fairly large dimensions of the refractive microlens (990-μm diam, 60-μm ...
A spectral collocation multi-domain scheme is developed for the accurate and efficient time-domain solution of Maxwell's equations within multi-layered diffractive optical elements. Special attention is being paid to the modeling of out-of-plane waveguide ...
The synthesis and spectroscopic characterization of the chromoionophoric poly(methyl methacrylate-co-N-(9-[10-methacryloylmethyl]anthrylmethyl)monoaza-18-crown-6) (4) copolymer is described. Complexation of K+ by extraction from aqueous medium w ...
The operation of a 92 GHz quasi-optical gyrotron having a resonator formed by a spherical mirror and a diffraction grating placed in -1 order Littrow mount is presented. A power of 150 kW with a Gaussian output pattern was measured. The Gaussian content in ...
