N2 - A novel optically tunable frequency-multiplying optoelectronic oscillator (OEO) to generate a high frequency microwave signal without employing an optical filter is proposed. The upper dual parallel Mach-Zehnder modulator (DP-MZM) integrated in a dual-polarization quadrature phase shift-keying (DP-QPSK) modulator is accurately biased to serve as an equivalent phase modulator (e-PM), which functions in conjunction with a phase-shifted fiber Bragg grating (PS-FBG) in the OEO loop as a high-Q microwave photonic band-pass filter, while the lower DP-MZM in the DP-QPSK modulator functions as a frequency multiplier for high frequency microwave signal generation by multiplying the oscillation signal generated from the OEO. An experiment is performed. A fundamental oscillation microwave signal with a carrier frequency from about 7.5 GHz to 12.5 GHz is generated, which is then frequency multiplied using the frequency multiplier. The phase noise of the generated microwave signal is also measured and studied.
