  • Patent number: 7321466
    Abstract: A diffraction grating having multiple holographic optical elements (HOEs), including a Dickson grating and at least one other volume phase grating (VPG). In typical embodiments, the multi-HOE grating is implemented to provide high dispersion, at least substantially uniform diffraction efficiency and at least substantially equal diffraction efficiencies for all polarizations across a wide range of wavelengths. The refractive index modulations of the Dickson grating's volume phase medium preferably have significantly greater spatial frequency than those of each other VPG of the multi-HOE grating. Typical embodiments of the multi-HOE grating can be manufactured at low cost with sufficiently small size and high dispersion (for both S-polarized and P-polarized radiation) to be useful in Dense Wavelength Division Multiplexing (DWDM) applications and other applications requiring high dispersion. The multi-HOE grating can be implemented as a transmissive or reflective grating.

  • Publication number: 20060007988
    Abstract: Apparatuses, systems and methods for transmitting and receiving modulated impulse radio signals. An impulse radio receiver includes a time base, a precision timing generator, a template generator, a delay, first and second correlators, a data detector and a time base adjustor. The time base produces a periodic timing signal that is used by the precision timing generator to produce a timing trigger signal. The template generator uses the timing trigger signal to produce a template signal. A delay receives the template signal and outputs a delayed template signal. When an impulse radio signal is received, the first correlator correlates the received impulse radio signal with the template signal to produce a first correlator output signal, and the second correlator correlates the received impulse radio signal with the delayed template signal to produce a second correlator output signal. The data detector produces a data signal based on at least the first correlator output signal.
