    摘要: A combined multiplexer/demultiplexer for use in optical communication systems is disclosed. The combined multiplexer/demultiplexer includes a plurality of waveguide arrays and a plurality of signal carriers, each disposed substantially symmetrically about an optical axis of the device. In operation, a signal carrier emits a multiple wavelength optical signal that is received and directed to a dispersion apparatus by a light focusing device. The dispersion apparatus diffracts the optical signal into selected spectral components and reflects the spectral components back to the waveguide arrays through the light focusing device. The signal processing, such as multiplexing and demultiplexing, performed by each waveguide array depends on their configuration. The waveguide arrays may be configured to substantially simultaneously multiplex and/or demultiplex the spectral components.

    摘要: An active device for dynamic control of lightwave transmission properties has at least one photonic crystal waveguide that has anti-reflection photonic crystal waveguides with gradually changed group refractive indices at both input and output side. An alternating voltage or current signal applied to two electrically conductive regions changes the refractive indices of the photonic crystal materials, introducing a certain degree of blue-shift or red-shift of the transmission spectrum of the photonic crystal waveguide. The output lightwave with frequency close to the band-edge of the photonic crystal waveguide is controlled by the input electric signal. Devices having one or more such active photonic crystal waveguides may be utilized as an electro-optic modulator, an optical switch, or a tunable optical filter.

    摘要: The present invention provides an optical apparatus having a multimode interference coupler configured to optically couple a strip waveguide to a slot photonic crystal waveguide. The multimode interference coupler has a coupling efficiency to the slot photonic crystal waveguide greater than or equal to 90%, a width that is approximately equal to a defect width of the slot photonic crystal waveguide, a length that is equal to or less than 1.5 μm, and interfaces with the slot photonic crystal waveguide at an edge of a period that gives a termination parameter of approximately zero. The optical apparatus may also include an insulation gap disposed between the multimode interference coupler and the slot photonic crystal waveguide, wherein the length of the multimode interference coupler is reduced by approximately one half of a width of the insulation gap.

    摘要: The present invention relates to the transmission of optical signals, and more particularly to wavelength division multiplexers and demultiplexers for optical signals. A wavelength division multiplexer device for use in an optical transmission system comprises a light input, one or more lenses, a substrate, one or more holographic optical elements, and two or more light outputs. The light input, the substrate, and the one or more lenses direct a light beam through the device. The one or more holographic optical elements act as transmission diffraction gratings and spatially separate the input light beam into dispersed light beams. Each light output receives one of the dispersed light beams. Multiple holographic optical elements may be stacked upon one another or separated by a substrate. Additionally, the substrate may comprise edges or parts that are beveled. Finally, the elements of the present invention may be rigidly coupled to each other, without intervening air space.
