摘要： A plane-parallel optical window is the spacer of single-cavity filters in the stack used for DWDM applications. Highly reflective quarter-wave stacks are deposited on each side of the optical window and the single-cavity structure so obtained is diced to produce a plurality of filters. Because the single-cavity structure has the same thickness over the entire window area and the quarter-wave-stack deposition process is carried out throughout under the same conditions, each single-cavity filter fabricated from the optical window has the same transmission wavelength and is therefore readily stackable for DWDM applications. Alternatively, an optical window with a thickness equal to one half that required for the spacer of a single-cavity filter is coated on a single side. The window is then divided in multiple identical components that can be combined in pairs by placing them in optical contact so as to form individual single-cavity filters with the same transmission wavelength.
摘要翻译：平面平行光学窗口是用于DWDM应用的堆叠中的单腔过滤器的间隔件。将高反射四分之一波长的叠层沉积在光学窗口的每一侧上，并且如此获得的单腔结构被切割以产生多个滤光器。由于单腔结构在整个窗口区域具有相同的厚度，并且在相同的条件下进行四分之一波长堆叠沉积处理，所以由光学窗口制造的每个单腔滤波器具有相同的透射波长，并且因此可以方便地为DWDM应用程序堆叠。或者，具有等于单腔过滤器的间隔件所需的一半厚度的光学窗口涂覆在单侧上。然后将窗口分成多个相同的部件，通过将它们放置在光学接触中可以成对地组合，以形成具有相同透射波长的单个单腔滤波器。

摘要： A four-fiber collimator is coupled to the optics of a single interleaver to produce the functionality of two co-packaged interleavers. Two fibers of the collimator are coupled to the core optics of a single interleaver to produce two pairs of output beams. The other two fibers of the collimators are coupled to receive the reflection output beams. The geometry of the optical fibers in the bundle is controlled to produce interleaver outputs with no offset. In another embodiment two fibers of the four-fiber collimator are coupled as inputs to and the other two fibers as outputs from a Fabry-Perot etalon. The geometry of the fibers and the focal length of the collimator are controlled to produce two outputs with peaks offset by a predetermined amount.

摘要： An interferometer includes a means for splitting, at a splitting location, an input light beam into a first beam and a second beam; and means for recombining, at a recombination location, the first beam and the second beam. The interferometer is designed such that the first beam will travel a first optical path length (OPL) from the splitting location to the recombination location, and the second beam will travel a second OPL from the splitting location to the recombination location and such that when the input light beam has been modulated at a data rate comprising a time interval, then the difference in optical path lengths between the first OPL and the second OPL is about equal to the time interval multiplied by the speed of light.

摘要： Beam splitter designs for interferometers provide a phase difference between the two resulting interference beams that are independent of the polarization status of the incident beam. The polarization independent phase coating is achieved by making the internal beam splitting coating of an unpolarized beam splitter to be symmetrical. A symmetrical coating will produce the phase matching condition, ΨSR−ΨSR′=ΨPR−ΨPR′=0.

摘要： Apparatus for detecting defects in a substrate comprises a laser for providing a laser beam, and a bi-cell photodiode comprising two cells. Circuitry coupled to the bi-cell photodiode provides a signal equal to (L−R)/(L+R), where L and R equal the signal strengths of the signals provided by the left and right photodiode cells, respectively. The photodiode is biased so that it exhibits reduced capacitance, and can provide increased output signal bandwidth.
