摘要： A plurality of channels of a wavelength division multiplexing system may be subjected to dispersion compensation in a fashion which enables tuning of the compensation for each individual wavelength channel. Moreover, the tuning may be done in a space-efficient fashion. The chirped Bragg gratings may be formed, for example, on a planar light circuit. Each grating may be heated to controllably adjust its dispersion compensation, in one embodiment of the present invention.

摘要： Optical circuits having a flat wavelength response are disclosed. A disclosed apparatus includes a first optical coupler, first and second optical waveguides optically coupled to the first optical coupler and a second optical coupler optically coupled to the first and second optical waveguides. The first optical coupler couples input light into a first portion and a second portion. The first and second optical waveguides receive the first and second portions of input light from the first optical coupler, respectively the second optical coupler couples the first portion of input light from the first optical waveguide and the second portion of input light from the second optical waveguide. The second optical waveguide may effect a fixed phase difference of one-half wavelength relative to the input light. The first and second optical couplers may have first and second wavelength dependences, respectively, where the second wavelength dependence is opposite the first wavelength dependence.

摘要： A structure (i.e. a segmented grating) which applies a designated complex-valued spectral filtering function to the input optical field and emits a filtered version of the input field in an output direction and a method for making such a structure. The segmented gratings fabricated in accordance with the present invention consist of a series of spatially distinct subgratings arrayed end to end. Each subgrating possesses a periodic array of diffraction structures (lines or more general elements). The overall transfer function of the segmented grating is determined by controlling (a) the spatial periodicity or frequency of each subgrating, (b) the amplitude of each subgrating, (c) the spacing between the last diffraction structure (or line) on each subgrating and the first diffraction structure (or line) of the successive subgrating, and (d) the optical path length and transparency through each subgrating, or each subgrating plus additional material layers utilized to control optical path length and transparency.

摘要： A method is described that involves identifying one or more images of respective one or more fixed markers. Each marker is positioned on or proximate to a display. The images appear on a pixilated sensor within a handheld device. The method also involves determining a location on, or proximate to, the display where the handheld device was pointed during the identifying. The method also involves sending from the handheld device information derived from the identifying of the one or more images of respective one or more fixed markers. The method also involves triggering action taken by electronic equipment circuitry in response to the handheld device's sending of a signal to indicate the action is desired.
