摘要： Miniature optical devices, including circulator array devices, are fabricated using thin film coating technology. A typical optical device includes two refraction elements arranged opposite each other along a propagation axis and coupled on opposite ends to first and second polarization orientation elements with first and second PBS elements are coupled to the first and second polarization orientation elements, respectively. The refraction elements include complementary Wollaston Prism elements or Rochon Prism elements. Each polarization orientation element includes a Faraday rotator element, and in some embodiments, a half-wave plate formed using thin film coating techniques. The Faraday rotator elements are periodically poled in some embodiments using selective poling techniques to create oppositely oriented magnetic domains so that polarization rotations of 45 degrees in both clockwise and counter-clockwise directions can be simultaneously achieved on the same magnetic garnet. Periodically etched half-wave plates are used in some embodiments.

摘要： Miniature optical devices, including circulator array devices, are fabricated using thin film coating technology. A typical optical device according to the present invention includes a spatial walkoff plate (SWP) coupled on opposite ends to first and second polarization orientation elements. First and second polarization beam splitter (PBS) elements are coupled to the first and second polarization orientation elements, respectively. The PBS elements are formed using thin film coating techniques and each includes an array of port coupling regions for coupling to an array of input/output fiber port assemblies. The SWP may be formed using thin film coating techniques or cut from a birefringent single crystal. Each polarization orientation element includes a Faraday rotator element, and in some embodiments, each also includes a wave plate formed using thin film coating techniques. The Faraday rotator elements are periodically poled in some embodiments using selective poling techniques to create oppositely oriented (bi-directional) magnetic domains so that polarization rotations of 45° in both clockwise and counter-clockwise directions can be simultaneously achieved on the same magnetic garnet. Periodically etched half-wave plates are used in some embodiments. Depending on the orientation of the optical axes of the SWP and the first and second PBS elements, the constituents of each polarization orientation element are designed and oriented so that the circulator device achieves a circulating operation with optical signals at an input port, i, coupled to one PBS element being passed to an output port, i+1, coupled to the other PBS element in a non-reciprocal manner.

摘要： The present invention provides for an optical waveguide device comprising a gratings, primarily in the form of fiber Bragg gratings, which are sampled, interleaved and chirped to achieve different functions. By interleaving sampled fiber Bragg gratings, each with a grating period which differs from the others by an amount corresponding to a multiple of a channel spacing, a predetermined and useful optical spectrum can be produced for the optical waveguide device. By making the sample periods for the fiber Bragg gratings different from each other, the resulting reflection spectrum has missing reflection peaks. A bandpass filter can be effectively created. Furthermore, by discretely varying the grating periods of sampled fiber Bragg gratings at intervals along the optical fiber containing the gratings, a more uniform optical spectrum is produced for the optical waveguide device. Finally, by chirping the sampling function of a sampled and chirped fiber Bragg grating, compensation for both dispersion and dispersion slope of a transmission fiber can be achieved.

摘要： Cholesteric liquid crystal cell units are used for reflecting or transmitting incident light responsive to control signals. A cholesteric liquid crystal cell unit has a first cholesteric liquid crystal cell and a second cholesteric liquid crystal cell. The second cholesteric liquid crystal cell respectively reflects or transmit lights from the first cholesteric liquid crystal cell responsive to a control signal when the first cholesteric liquid crystal cell reflects circularly polarized light of one state or transmits the incident light. In one embodiment of the cell unit, a &pgr;-phase waveplate element is located between the first and second cholesteric liquid crystal cells. With the cholesteric liquid crystal cell units, devices such as optical switches, and WDM add/drop multiplexers, and optical switch systems with arrays of input and output optical fibers between a switching matrix formed by the cholesteric liquid crystal cell units, may be constructed.

摘要： The invention provides a package which varies the tension within a fiber Bragg grating (or other fiber-based optical device) by resilient deflection of a fiber support member through differential thermal expansion, thereby allowing the temperature/tension characteristics of the package to be tailored so as to provide the desired optical characteristics throughout a wide temperature range. The fiber tension/temperature correlation may be tailored using the linear coefficient of expansion of two different materials, by varying the resilient flexibility of a beam supporting the fiber, by varying a length of an arm extending from the beam to the fiber, by varying the resilient strength of the arm, and the like. By relying on the resilient deformation of a flexible fiber support structure, the present invention provides a large number of degrees of freedom within the package design parameters. Where such precise control over the temperature/tension correlation is not required, the invention provides alternative compensation packages which can be mass-produced easily.
