Photonics-based microwave switching using optical single sideband (OSSB) wavelength conversion in a semiconductor optical amplifier (SOA) is proposed and demonstrated. By using the joint four-wave mixing and self-phase modulation effects in the SOA, the scheme can simultaneously realize the OSSB signal generation and photonic microwave switching, which can minimize the switching crosstalk, since the...
CRH (China Railway High-speed) has become the preferred option to travel today with the increase purchasing power of the public. The need to enhance the overall wireless network coverage and quality along CRH railway track has become the important milestone of existing operators. Thus, intense studies had been carried out to differentiate CRH travelers from normal mobile users in order to provide...
Microwave switching is of great importance in satellite communications to realize function switching, signal routing, and system reconfiguration. Photonic approaches to realize the microwave switching have advantages in terms of wide bandwidth, high switching speed and immunity to EMI. In this paper, we present a review on the recent advances of the photonic microwave switching for satellite communications...
Photonic switching of RF signals based on optical single sideband (OSSB) wavelength conversion using a semiconductor optical amplifier (SOA) for radio-over-fiber applications is proposed and demonstrated. The scheme realizes OSSB signal generation simultaneously with the photonic microwave switching based on self-phase modulation (SPM), cross-gain modulation (XGM) and four-wave mixing (FWM) effects...
