摘要： An apparatus for exposing an article to radiant energy has a rotating carousel having an article support in a support sector defined between a first energy-blocking feature of the rotating carousel and a second energy-blocking feature of the rotating carousel. An actuator is energizable to rotate the carousel and to revolve the article support along a circular transport path. An enclosure has a stationary hood that defines an enclosed sector of the transport path and an unenclosed sector of the transport path. There is at least a first radiant energy source energizable to direct the radiant exposure energy toward the carousel along the enclosed sector of the transport path.

摘要： In accordance with the invention, a filter is fabricated by a modified form of the process disclosed in U.S. Pat. No. 7,068,430. In particular, the method is modified to take into account the effect of absorption by filter material. The method is exemplified by the fabricating of an ultraviolet light transmission filter for transmitting a band within the range 230-320 nanometers. The resulting filter comprises plurality of hard-coating, thin-film layers of alternating high and low index of refraction. The improved filter provides high transmission, sharp edge slopes, and deep and extended out-of-band blocking. As compared with currently available filters, the filter provides transmission up to three or more times greater, edge slopes up to four times sharper, and deep extended out-of-band blocking extending further, even through the visible range.

摘要： Thin-film interference filters are constructed with a generalized pattern of layers differing in both thickness and refractive index to produce spectral responses appropriate for adjusting optical power among a plurality of different wavelength channels. Each of the layers is composed of unit sub-layers having thicknesses equal to a quarter-wavelength thickness of a monitoring beam. Interference fluctuations of the monitoring beam associated with the deposition of the unit sub-layers enable a gain-flattening filter to achieve greater manufacturing accuracy by exploiting self-correcting effects of “turning point monitoring” techniques.

摘要： The present invention is predicated upon the discovery by applicants of a relationship describing thermal decay of radiation-induced index changes and a mechanism which permits stabilization by accelerated aging. Specifically, the induced index change decays in proportion to 1/(1+At.sup..alpha.) where A and .alpha. are functions of temperature, and the decay can be accelerated by heat treatment. As a consequence, the extent of decay can be determined for arbitrary time and temperature and, significantly, an appropriate heat treatment can be scheduled for making a device stable within predeterminable limits.

摘要： A device and method for compensating for chromatic dispersion in an optical signal. The optical signal is coupled between an optical waveguide of a type having (i) a fundamental-mode waveguide and (ii) a higher-order mode waveguide surrounding the fundamental-mode waveguide, wherein different effective indexes of refraction are associated with the fundamental-mode and higher-order mode waveguides. The device comprises a transmissive, long-period optical grating disposed along a length of the optical waveguide and has a receiving end and a transmitting end. The grating is chirped between the ends along a light conducting axis of the optical waveguide such that different wavelengths of the optical signal are coupled to the fundamental-mode and higher order mode waveguides at different points along the length of the grating so that chromatic dispersion is corrected at the transmitting end.
