  • Photonic generator of ultra-wide band millimeter wave
    Patent number: 8483578
    Abstract: A photonic generator is provided. The photonic generator uses ultra-wide band millimeter wave (MMW) for generating a high-power ultra-broad band white noise. Thus, the present disclosure can be used for failure detection of instantaneous all-band device, noise detection of instantaneous all-band amplifier and mixer, wide-band cipher transmission, pseudo-random bit generation, ADC dithering of analog-digital converter, saturation power test of wide-band optical communicator, system noise detection of MMW receiver, and gain and phase detection of MMW interferometer.
    Type: Grant
    Filed: November 18, 2010
    Date of Patent: July 9, 2013
    Assignees: National Central University, National Taiwan University
    Inventors: Jin-Wei Shi, Tzi-hong Chiueh, Nan-Wei Chen, Feng-Ming Kuo, Hsuan-Ju Tsai, Hsiao-Feng Teng
  • Optoelectronic switch transmitter using millimeter wavelength
    Patent number: 8306428
    Abstract: An optoelectronic switch using millimeter wavelength (MMW) is provided. An r voltage pulse is applied to a device under test (DUT) for switching the photo-generated MMW power The DUT is operated under reverse bias. An optical light source with modulated MMW envelop is injected on to DUT for MMW power generation. Thus, based on change of the reverse bias, speed is violently changed and the MMW optoelectronic switch is thus obtained.
