Abstract:	摘要： Based on the frequency-to-time mapping approach, we generate frequency-modulated millimeter-wave (MMW) pulses with central frequencies up to the W-band by a shaped optical pulse excitation of an MMW photonic transmitter with an ultrawide band photodiode as its key component. A coherent detection is achieved via a terahertz time-domain spectroscopic setup. Two different kinds of chirped MMW waveforms are generated; one is a linearly chirped sinusoidal pulse and the other is produced by a frequency-stepped modulation. Through appropriate optical spectral design, the frequency-chirped MMW pulses with instantaneous frequencies sweeping from 120 to 60 GHz, and a time-bandwidth product of ~ 25 is experimentally demonstrated. 其他題名： LPT 出版者： IEEE 出版日期： 2012-08-15 出處： IEEE photonics technology letters, 2012-08, Vol.24 (16), p.1437-1439 資源來源： IEEE Electronic Library (IEL) 識別號： ISSN: 1041-1135 識別號： EISSN: 1941-0174 識別號： DOI: 10.1109/LPT.2012.2205914 識別號： CODEN: IPTLEL
