“…Photonic generation of spectrally pure microwave signals has drawn great attentions in the past decades. Due to the wide bandwidth and extremely low loss characteristics, photonic techniques are capable of generating stable microwave signals up to 100 GHz [1]- [3]. For example, optoelectronic oscillator (OEO) that achieves an unprecedented phase noise performance of À163 dBc/Hz at 10 kHz offset from a 10 GHz carrier has been reported [4].…”

Self-phase locked loop (SPLL) through long optical delay lines is investigated for improving the phase noise of the optoelectronic oscillator (OEO) and the voltage-controlled oscillator (VCO). This paper features analytical modeling of close-in to carrier phase noise of oscillators employing SPLL technique using single and multiple delay loops. Experimental results are also provided to verify the analytical modeling and explore critical circuit design parameters to achieve substantial phase noise reduction. Performance comparison is presented for SPLL using electrical phase shifter, Mach-Zehnder modulator (MZM)-based phase shifting, and electrical VCO. Phase noise reduction of 65 dB at 1-kHz offset is achieved for an electrical VCO employing a dual-loop SPLL with 3-and 5-km optical fiber delay lines, whereas the phase locking based on MZM and electrical phase shifter provided 20-and 38-dB reductions at 1-kHz offset for an OEO, respectively.

“…O PTOELECTRONIC devices have been used to generate continuous-wave radio-frequency signals using a laser with an external electronic feedback [1], an electronic circuit controlled by the photoconductivity effect [2], an optical wave mixing in hetrojunction bipolar transistor [3], an optical frequency comb generator with a uni-travelling-carrier photodiode [4], and a low-frequency square wave modulation of a laser diode [5]. The electrical wave generated in those works was a low-noise continuous-wave signal with a frequency that could be controlled over a broad frequency regime.…”

We study a new method to synthesize high-frequency complex microwave and millimeter-wave pulses using dispersion, Kerr effect, and group velocity delay in optical fiber systems. The profile of the generated pulses can be controlled by changing the parameters of the optical system. Nonlinear propagation effect in fibers can be used to generate electrical pulses with an extremely broad spread spectrum. Soliton trapping can be used to generate electrical pulses with a controllable frequency. Implicit results are given when dispersion or nonlinear effect can be neglected. Generation of electrical pulses with a controllable microwave frequency is demonstrated experimentally using a Mach-Zehnder interferometer and a chirped fiber Bragg grating.
