    摘要： An example embodiment may include an interferometer. The interferometer may include a multimode waveguide with an input waveguide optically coupled to a first side of the multimode waveguide, for feeding a light signal to the multimode waveguide. The interferometer may also include a first waveguide at one end optically coupled to a second side of the multimode waveguide, and at the other end terminated by a first waveguide mirror. The interferometer may also include a second waveguide at one end optically coupled to the second side of the multimode waveguide and at the other end terminated by a second waveguide mirror. The multimode waveguide may be adapted to distribute the light signal towards the first and second waveguide mirror via the first waveguide and via the second waveguide.

    摘要： Fiber-optic beam routing and amplitude control modules based on a unique fault-tolerant scheme using a macro-pixel to control an optical beam are proposed. The unique macro-pixel method involving multiple device pixels per beam inherently provides a robust digital technique for module control while adding to the optical beam alignment tolerance and resistance to catastropic failure for the overall module. The macropixel approach solves the speed versus alignment and failure sensitivity dilemma present in single pixel element based optical micromechanical systems (MEMS). Specifically proposed are fault tolerant fiber-optic attenuators and switches using several microactuated micromirrors per optical beam. Transmissive and reflective module geometries are proposed using small tilt and small distance piston-action micromirrors, leading to fast module reconfiguration speed fiber optic signal controls. The macro-pixel design approach is extended to other pixel technologies such as polarization rotating pixels. The proposed fiber-optic attenuator and switch designs can be extended to realize a complex network of multiple attenuators and switches that can be applied to N-wavelength multiplexed fiber-optic networks.

    摘要： A monolithic waveguide/MEMS switch is disclosed that has a waveguide portion and a MEMS mirror portion fabricated on a single substrate, such as a as a silicon-on-insulator wafer. The monolithic waveguide/MEMS switch adjusts the phase of an optical signal by varying the position of one or more moveable mirrors. The mirror portion includes a mirror having a reflective surface that is attached to at least one MEMS actuator to achieve in-plane motion of the mirror (moves parallel to a plane of said at least one waveguide). In one implementation, the MEMS actuator is embodied as a known comb drive actuator. The phase adjustment techniques of the present invention may be employed in various optical devices, including wavelength selective optical switches that support multiple optical channels.

    摘要： Input light is split by a PBS into orthogonal polarized waves. One of the polarized waves is reflected by a mirror HR, and input to a 7λ/8 plate. The other is phase-controlled by a phase controller, and input to the 7λ/8 plate. The respective light beams to which a phase bias is applied by the 7λ/8 plate are input from a 2R mirror having reflectances that differ depending on a polarized wave to a GT resonator. The light beams output from the GT resonator again pass through the 7λ/8 plate, inversely travel the original optical path, and enter the PBS. Then, the light beams are output from an output 1 or 2 depending on a polarized wave.
