摘要：

We propose a microwave photonic link to transmit a dualchirp microwave waveform over fiber with compensation of dispersion-induced power fading. In a center office (CO), we use a polarization-dependent dual-parallel Mach -Zehnder modulator (DPMZM) which is driven by a radio frequency (RF) carrier and a baseband single-chirped waveform to realize carrier-suppressed dual-sideband (CS-DSB) modulation at two orthogonal polarization states. When the CS-DSB optical signal is detected by a photodetector (PD) at a base station (BS), the dual-chirp waveform is generated. However, along with the transmission to different BSs before emission, the chromatic dispersion of fiber will cause power fading. In our link, we can simply adjust the polarization controller (PC) in each BS to compensate for the dispersion-induced power fading for different transmission distances and RF carrier frequencies. Besides, the link can realize one to multitransmission with shared dual-chirp microwave source in CO for radars. The proposed scheme is theoretically analyzed and experimentally verified.
