摘要： The present invention provides a dense wavelength division multiplexer for separating an optical signal into optical channels. It includes at least one birefringent plate (718, 720), and a polarization beam splitter (702) optically coupled to the at least one birefringent plate, the polarization beam splitter and at least one birefringent plate for separating one or more of the plurality of optical channels, where the separating is based on the polarity of the plurality of optical channels. In a preferred embodiment, the mechanism of separating includes birefringent wedge plates, a polarization beam splitter (702) and two non-linear interferometers (722, 724), with the birefringent wedge plates (718, 720) disposed between the polarization beam splitter (702) and the input and output paths. It also provides an ease in alignment and a higher tolerance to drifts due to the increase in the widths of the pass bands and also provides an improved separation of channels relative to other wavelength division multiplexers employing polarization beam splitters.

摘要： An optical wavelength division multiplexing (WDM) device comprising optical components that are integrated together to provide an optical WDM that does not require circulators, that has simplified alignment and that is relatively low in cost. The WDM device comprises an integrated port separator (251), a dispersive element (28) and a reflector (30). The integrated port separator comprises various optical components that spatially separate the polarization components of a light beam input (I1,I2) through an input port of the integrated port separator. The spatially separated polarization components are output from the integrated port separator and impinge on the dispersive element, which spatially separates the wavelengths associated with the polarization components impinging thereon. The spatially separated wavelengths then impinge on the reflective element and are reflected with angles of polarization that depend on the state of the reflective element. The reflected polarization components maintain their respective wavelengths when they are reflected. However, when they are reflected, they are directed along a path through the integrated port separator that depends on the angles of polarization of the reflected polarization components, which depends on the state of the reflective element being rotated or not rotated.

摘要： The present invention relates to an interferometer useful in the interleaving and deinterleaving of optical wavelength channels. Typically the invention comprises a beamsplitter and two resonators, e.g. GT etalons or ring resonators. The beamsplitter splits an input beam of light into a first sub-beam directed to follow a first path and a second sub-beam directed to follow a second path. The first resonator has a first effective cavity length and receives the first sub-beam. The second resonator has a second effective cavity length and receives the second sub-beam. The first path and the second path have an effective optical path difference approximately equal to one-half the first effective cavity length. In one embodiment, the front plates of the GT etalons each have a different reflectivity, and are selected to provide a desired spectral response. In another embodiment, the two resonators are slightly de-phased from one another such that the positive dispersion slope of the first resonator is aligned with the negative dispersion slope of the second resonator. Polarization-based versions of the invention are disclosed, in which a single resonator receives both sub-beams, which are orthogonally polarized. Single etalon versions of the invention are also possible, in which a beam is separated into sub-beams (i.e. reflected and transmitted beams) within a non-linear interferometer, and then re-combined outside the interferometer with the appropriate effective optical path length delay therebetween.

摘要： An optical multiplexer/demultiplexer for fiber optical communication is disclosed. The device includes a collimator (21), configured to collimate a beam of wavelength-division-multiplexed signal received from a fiber (20); a splitter (23) for dividing the beam into two parallel beams which are polarized 90° from each other; a retarder, such as a half-wave plate, for rotating the polarization direction of one of the beam by 90° so that both beams are polarized in the same direction; a beam steerer, such as a prism (25), for modifying the diameter in the direction parallel to the polarization direction and for modifying the propagation direction; a wavelength dispersing element, such as a diffraction grating (27), for separating each of beams into a plurality of beams, each having a different center wavelength and propagating along a different angular direction. The optical elements in the multiplexer/demultiplexer are arranged in such a way to direct the diffracted beams through the optical elements, in reverse order, resulting in a plurality of beams, which may be launched into optical fibers (33). The parameters of the optical elements may be chosen to be suitable for multimode dense WDM applications using single-mode transmission fiber.

摘要： An M X N routing optical matrix switching method and device provide a routing optical Crossbar network system. They provide a routing parallel optical channel network with performance of non-block and a parallel optical channel routing combination. Each input port is provided with N parallel optical channels, respectively, leading to the order number end of each output port. Consequently, the signal beams from each input port can select one of N independent optical channels in complete non-block to be transmitted to the output order number port. Then, M parallel optical channels, desired to reach to identical one output port, are incorporated into one parallel optical channel by routing combination. Thus, the signal beams from the input fibers are coupled into the output fibers in high-efficiency. An optical matrix switching device consists of a collimated unit of one dimension fiber array, a crystal unit for converting random polarization beam into linear polarization beam, a routing parallel optical channel network, a routing combination unit of parallel optical channel, and a coupling unit of one dimension fiber array. The device has various advantages of simple structure, small size, lower insertion loss, good scalable, switching rate of millisecond or microsecond order, unidirection, bidirection and broadcast functions. A module of M×N (M=2 m , N=2 n , m and n are nature numbers) optical routing matrix switching can be developed, and can widely serve for varieties of all-optical cross connection, optical add/drop OADM and optical wavelength route OXC equipment in the field of DWDM optical communication.
