Semiconductor saturable absorber mirror (SESAM) mode-locked all-polarization maintaining (PM) fiber oscillator with a fundamental repetition rate up to 1 GHz centered around1558 nm was demonstrated. With a 450 mW incident pump power, the oscillator is operating at the soliton mode-locked regime due to intracavity anomalous dispersion. The spectral width and compressed pulse duration is 9.4 nm and...
A novel optical pulse generator with high-rate and low-jitter is proposed based on the optoelectronic oscillator using a cascaded polarization modulator and phase modulator. Optical pulses with 10 GHz repetition rate and 29 ps width are demonstrated. According to the single-sideband phase noise of the generated microwave signal, 169 fs time jitter of the generated pulses in the 100 Hz to 1 MHz frequency...
A novel compact optoelectronic oscillator employing Fabry-Perot (FP) resonator based on travelling-waveguide-type electro-optic (EO) modulator has been proposed and experimentally demonstrated. The EO modulator based FP resonator is used as the optical energy storage and mode selection elements, which can greatly reduce the system complexity by replacing long optical fiber and microwave narrow bandpass...
We evaluate external cavity pulse compression of giant chirp oscillators and demonstrate third-order dispersion has limited influence on the minimum compressed pulsewidth. Furthermore, we propose an effective method to compress the pulse to transform-limited value.
A photonic system is proposed to calibrate the instantaneous frequency and glitches of a fast frequency sweeping oscillator using a pseudo random bit sequence (PRBS) frequency comb. Its performance is demonstrated by simulations and experiments. A vector signal generator (Agilent E8257D), whose frequency ranges from 0.5 to 2.5 GHz and from 2.5 to 5 GHz, respectively, is calibrated. The deviation from...
A novel photonics approach to the characterization of instantaneous frequency and glitches of sweeping oscillators is proposed and demonstrated based on a PRBS frequency comb. The analog sweeps of a vector signal generator, whose sweeping ranges are 0.5 GHz to 2.5 GHz and 2.5 GHz to 5 GHz respectively, are calibrated using the proposed method, and the glitches of sweeping is also identified. The proposed...
