    摘要: The present invention is directed to an apparatus that drives a lighting system with multiple lamps. A phase shift mechanism is produced either by a digital method, an analog method, or a mixture of the two methods. In a digital method, phase shifts are generated by digital circuits comprising counters, a divider, an adder, and a comparator. The digital circuits analyze the signal and use the necessary information to form a series of phased driving signals. In an analog method, phase shifts are generated by analog circuits comprising ramp waveform generators, comparators, and at least one shot generator. Also, an apparatus for driving a lighting system with multiple lamps can be realized by mixing the two methods mentioned above.

    摘要: A (de)multiplexer for use in optical communications systems for multiplexing and demultiplexing an optical signal consisting of optical channel(s) of different wavelength(s) includes a multiplex optical waveguide propagating a plurality of optical channels and a plurality of single channel optical waveguides, each propagating a single channel. Each of the waveguides has a receiving/transmitting end. A diffraction grating is optically coupled between the multiplex optical waveguide and the single channel optical waveguides for diffracting an optical signal between the receiving/transmitting end of the multiplex optical waveguide and the receiving/transmitting end of the single channel optical waveguide. The grooves of the diffraction have spacing which varies according to an algorithm such that a portion of the optical signal diffracted by each groove is offset in a direction of dispersion relative to the portions of the optical signal diffracted by the other surfaces to broaden the transmission band at the receiving/transmitting ends of the single channel and multiplex optical waveguides. A method for fabricating a grating as described above includes etching grooves having spacing which varies according to the algorithm such that a portion of the optical signal diffracted by each surface is offset in a direction of dispersion relative to portions of the optical signal diffracted by each other surface.
