Abstract :
A tunable optoelectronic oscillator (OEO), which achieves stimulated Brillouin scattering (SBS) by injecting a pump laser into an upper single sideband (USSB) modulated signal, is designed. Through simply adjusting the wavelength of the pump laser, the frequency tunability of the OEO is realized. An experiment is performed. A microwave signal with a frequency-tuning from 2.4 to 10.765 GHz is generated, and the power is at least 38 dB higher than its harmonic components for all the frequencies. In addition, the single-sideband phase noise of the generated microwave signal is also investigated.
