    摘要： A microstructured optical waveguide that supports the propagation of an optical signal of a desired wavelength is described. The optical waveguide includes a core region formed from an optically nonlinear material having a &ggr; of at least about 2.5×10−19 m2/W at 1260 nm. The optical waveguide also includes a cladding region surrounding the core region, the cladding region including a bulk material and a lattice of columns located in the bulk material, the lattice of columns having a pitch, and each column having a cross-sectional area. The pitch of the lattice and the areas of the columns are selected such that the dispersion of the optical signal at the desired wavelength is within the range of about −70 ps/nm-km to about 70 ps/nm-km.

    摘要： Disclosed is a photonic band-gap crystal waveguide having the physical dimension of the photonic crystal lattice and the size of the defect selected to provide for optimum mode power confinement to the defect. The defect has a boundary which has a characteristic numerical value associated with it. The ratio of this numerical value to the pitch of the photonic crystal is selected to avoid surface modes found to exist in certain configurations of the photonic band-gap crystal waveguide. Embodiments in accord with the invention having circular and hexagonal defect cross sections are disclosed and described. A method of making the photonic band-gap crystal waveguide is also disclosed and described.

    摘要： A plurality of active gain material (93) is disposed in an active interface portion (44) of a dielectric band-gap cladding confinement region (22) adjacent to a dielectric core (12) of a photonic band-gap crystal fiber (20), wherein during operation, the plurality of active gain material (93) absorbs the pump energy and stores the pump energy as a potential energy storage for stimulation by EM energy in a second guided mode at a second frequency in a second range of frequencies for overlapping with the first guided mode of the core (12) such that the surface defined by an interface between the photonic band-gap cladding (22) and the dielectric core (12) that supports at least one surface mode propagating at that interface (44) overlaps the active interface portion of the dielectric cladding confinement region and a state associated with the dielectric core (12).

    摘要： An audio system for use with an electromechanical apparatus having a device coupled to the audio system, the device having a mechanical resonance stimulated by spectral components of vibrations radiated by the audio system, which includes an input for receiving audio signals and a gain reducer. The gain reducer includes a detector detecting in the audio signal the presence of the spectral components that excite the mechanical resonance and also includes a gain cell reducing the gain of said audio signals, either broadband or narrowband, responsive to the detector.
