摘要： We demonstrate a novel technique for photonic generation of few-cycle millimeter-wave (MMW) pulse using a WR-10 waveguide and near-ballistic unitraveling carrier photodiode (NBUTC-PD)-based photonic-transmitter-mixer (PTM). A 2.5-cycle MMW pulse is generated by simultaneously exciting the PTM optical port with ~100-GHz optical MMW sinusoidal signal and the intermediate-frequency (IF) port with a 25-ps electrical short pulse, respectively. Compared to results using femtosecond optical short pulses to directly excite the PTM (without E-O signal mixing), our approach is capable of providing much less signal distortion, eliminating the ringing oscillation in the tail of response, a much shorter pulse duration, and a higher peak power. 其他題名： JPHOT 出版者： IEEE 出版日期： 2012-08-01 出處： IEEE photonics journal, 2012-08, Vol.4 (4), p.1071-1079 資源來源： Directory of Open Access Journals (DOAJ) 識別號： ISSN: 1943-0655 識別號： ISSN: 1943-0647 識別號： EISSN: 1943-0647 識別號： DOI: 10.1109/JPHOT.2012.2204733 識別號： CODEN: PJHOC3
