摘要： Disclosed herein are embodiments of a solar-activated photochemical fluid treatment system, some of which comprise a fluid vessel, a porous enclosure positioned inside of the fluid vessel, a porous enclosure positioned inside of the fluid vessel, a fiber substrate contained within the enclosure, and a semiconductor photocatalyst coupled to the fiber substrate. The fluid vessel can be configured to contain a fluid in contact with the photocatalyst such that the fluid treatment system, responsive to solar radiation applied to the photocatalyst and to the fluid in the vessel, induces photochemical modification of contaminants and living organisms in the fluid. Related methods are also disclosed.

摘要： A cavity thickness compensated etalon filter. A tuning medium is placed in a Fabry-Perot etalon cavity. The index of refraction of the tuning medium varies as a function of voltage applied across the medium. The etalon is formed of two generally flat substrates disposed substantially parallel to one another. Each substrate has a layer of conductive material within the cavity adjacent the substrate. Each substrate also has a layer of reflective material within the cavity adjacent the substrate. At least one layer of reflective material is only partially reflective so as to enable light to pass into and out of the cavity. Liquid crystal material may be used as a tuning medium in the cavity. In the case of liquid crystal material, the etalon also comprises an alignment layer disposed within the cavity adjacent each substrate to pre-order the liquid crystal material. Means are provided for selectively varying the profile of the voltage across the tuning medium so as to compensate for variation in flatness and separation of the etalon substrates. Means are also provided to the render the filter polarization insensitive.

摘要： An ultra-short optical pulse source uses a gain-switched laser diode with a dispersive delay line to compress the optical pulse output from the laser diode, the gain-switched laser diode having particular spectral characteristics. The gain-switched laser diode may be tested by energizing it with a continuous wave signal at or near the lasing threshold level. The resulting spectrum is examined for the presence of satellite spectral intensity features. Those gain-switched laser diodes that exhibit a spectrum having all satellite spectral features below a predetermined level with respect to the intensity of a principal spectral component are selected for use in the ultra-short optical pulse source.
