    Photonic Measurement of Microwave Frequency With Low-Error based on an Optomechanical Microring Resonator

    Photonic Measurement of Microwave Frequency With Low-Error based on an Optomechanical Microring Resonator by Li Liu, Huaqing Qiu, Zhi Chen, Zhihua Yu

    Published 2017-01-01

    We propose and experimentally demonstrate photonic measurement of microwave frequency by utilizing an optomechanical microring resonator (MRR). The pump powers injected into the MRR would result the resonance red-shifts based on nonlinear effects. In the case of optical single sideband modulation, t...

    Frequency-Hopping Microwave Generation With a Large Time-Bandwidth Product

    Frequency-Hopping Microwave Generation With a Large Time-Bandwidth Product by Feng Zhou, Xu Wang, Siqi Yan, Xiao Hu, Yuguang Zhang, Huaqing Qiu, Xi Xiao, Jianji Dong, Xinliang Zhang

    Published 2018-01-01

    We propose and demonstrate an approach to generating large time-bandwidth product (TBWP) frequency-hopping (FH) microwave waveforms by using an ultra-high-quality factor (Q) silicon microring resonator (MRR) with thermal tuning. An ultra-high-Q MRR (Q &#x223C; 10<sup>6</sup>) is used...
