An optically tunable frequency-doubling Brillouin optoelectronic-oscillator using a dual-electrode Mach-Zehnder modulator (DEMZM) is presented. To achieve frequency-doubling, the DEMZM is biased at the maximum transmission point and only one of its electrodes is driven by the oscillation signal, whose frequency is determined by the stimulated Brillouin scattering effect in a high nonlinear dispersion-shifted...
A simple realization of frequency-doubling optoelectronic oscillator (OEO) using a phase modulator and a chirp fiber Bragg grating (CFBG) is proposed and experimentally demonstrated. In this OEO configuration, the phase modulator in combination with an optical filter is working as doubled-sideband phase modulation to produce a frequency-doubling microwave signal, while the CFBG ensures the oscillation...
An optically tunable frequency-doubling optoelectronic oscillator (FD-OEO) based on stimulated Brillouin scattering (SBS) and carrier phase-shifted double sideband (CPS-DSB) modulation is proposed and demonstrated. SBS effect provides narrowband filtering for the OEO to generate an oscillation signal with frequency equal to the Brillouin frequency shift, while a CPS-DSB modulation by using a dual-parallel...
