摘要： A packaged microelectromechanical device having a housing with a plurality of ports. A bundle of a plurality of optical fibers is mounted in one of the plurality of ports by a welded or brazed flange. An array-type microelectromechanical device is mounted in another port of the housing by a welded or brazed flange and includes a plurality of elements adapted for interacting with the plurality of optical fibers, whereby information may be transmitted into the housing via one of the optical fibers and may be transferred out of the housing via another of the optical fibers. The array-type microelectromechanical device has a plurality of electrical control pins protruding outside the housing. A pair of windows in the housing provides ports for optical sensory signals for the array-type microelectromechanical device. Two conduits for providing pressurized inert gas are mounted in the housing by welded or brazed flanges. The housing provides a hermetically sealed enclosure for the bundle of the plurality of optical fibers, the windows, the array-type microelectromechanical device, and the conduits. The pressurized inert gas is used to remove dust and moisture during assembly but remains in the finished assembly. Helium in the gas enables detection of leaks.

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.

摘要： An optical multiplexing/demultiplexing device has a structure wherein a curved waveguide for input, linear waveguides for output, and a planar waveguide are provided within a substrate. The curved waveguide is discontinuous, and the curved waveguide and planar waveguide are separated from each other with an equal interval interposed therebetween. A light signal that is input to the curved waveguide is reflected by discontinuous surfaces of the curved waveguide. Afterwards, the respective reflected light signals are distributed to corresponding linear waveguides through the planar waveguide for every wavelength and focused thereon. Further, the light signals of the respective wavelengths, which are input into the linear waveguides, are multiplexed by and focused on the discontinuous portions of the curved waveguide.

摘要： An imaging arrangement technique is used to align a first waveguide on a first wafer to a second waveguide on a second wafer. The adaptive imaging arrangement is used on both the first and second waveguides when the first and second wafers are orthogonal to each other. In one embodiment, my imaging arrangement is used in an N×N optical cross-connect constructed using orthogonal abutting input and output planar arrays of N switches. If N is not too large, the optimum construction involves only two stages of trees, each incorporating an adaptive imaging arrangement allowing the input and output trees to be directly joined together without need for precise alignment.

摘要： In accordance with the invention, an optical all-pass filter comprises a substrate-supported multilayer waveguiding structure comprising a first layer including a waveguiding optical ring resonator, a second layer including an optical grating optically coupled to the ring resonator, and a third layer including a relatively straight waveguide optically coupled to the grating. The waveguide can be made with standard index material matched to an optical communication system, and the ring can be made of higher index material. The grating sandwiched between them provides phase matching between these two index mismatched structures, facilitating efficient power transfer between them.

摘要： In a method and a device for extracting signals out of a glass fiber without any detectable interference occurring, in particular without the signals propagating through the glass fiber experiencing any transmission loss, light that emerges laterally from the glass fiber due to scattering (Rayleigh scattering) processes, which are in existence anyway, is directed at a photodetector. In the process, the emerging light can be directed by focussing elements at the photodetector or at the input face of another glass fiber. In addition, the emerging light can be directed both directly as well as via at least one reflector at the photodetector.
