    摘要: Interleaver/deinterleaver apparatuses for combining/separating optical channels are described. An interleaver/deinterleaver apparatus is described as folded when an optical signal is directed through a single crystal multiple times. Double-pass refers to the optical signal following a (folded) path through the apparatus twice. When operating as an deinterleaver, the interleaver/deinterleaver separates an optical signal (e.g., WDM signal) into subsets of optical signals (e.g., channels). In one embodiment, deinterleaving optical signals separates an optical signal into even and odd International Telecommunications Union (ITU) channels. When operating as an interleaver, the interleaver/deinterleaver mixes subsets of optical signals (e.g., channels) into a multiplexed (e.g., WDM) optical signal. The interleaver/deinterleaver apparatus can be used to increase the bandwidth of an optical network. For example, the interleaver/deinterleaver can be used to interface components designed for a first channel spacing (e.g., 100 GHz) to components designed for a second channel spacing (e.g., 200 GHz). In one embodiment, interleaveing combines even and odd ITU channels into a single optical signal.

    摘要: A method and device is disclosed for dispersion compensation of an optical signal having periodic dispersion within a multi-channels system. For example interleaved optical channels often exhibit dispersion having a characteristic that is repeated in adjacent channels. By providing a periodic device that allows for polarization dependent routing of an interleaved signal to allow for multiple passes of said signal through a multi-cavity GT etalon, having a free-spectral range that corresponds to the channel spacing, the dispersion in the interleaved signal can be lessened and practically obviated or balanced to a desired level. This invention provides a device and method to achieve that end.

    摘要: Interleavers are a useful tool in wavelength division multiplexing (WDM) to separate a signal with closely spaced channels into two signals, e.g. odd and even ITU channels, each with twice the channel spacing. Alternatively, two signals with a large channel spacing can be combined into a single beam with half the channel spacing. The invention relates to an optical interferometer using rhomb prisms as resonant cavities, which, when properly designed, provide the necessary phase shifts for interleaving or de-interleaving sets of optical wavelength channels. The present invention utilizes the differential phase shift between orthogonally polarized components induced by total internal reflection (TIR) off the surfaces of the rhomb prisms. Dispersion reducing techniques are also disclosed, including multiple rhomb interleavers and multi-pass rhomb interleavers.

    摘要: Conventional retroreflection mirrors in the form of right angle prisms are quite sensitive to beam position and beam angle errors. Manufacturing and assembly tolerances are also a cause of concern in conventional devices. Accordingly, the present invention solves these aforementioned problems by providing a retroreflection device comprising: a beam director, preferably in the form of a Wollaston prism; a polarization rotator, preferably in the form of a quarter wave plate; and a flat reflective surface, such as a plane mirror. The device of the present invention is far less sensitive to beam angle alignment and is completely independent of the beam position. The present invention is particularly useful as a beam splitter for directing orthogonally polarized beams of light back along parallel paths in an interleaver apparatus.
