title: Multiwavelength 25-GHz picosecond pulse generation with phase modulation and double-side Mamyshev reshaping.
abstract: We demonstrate a simple, robust, and cost-effective method of generating high-speed multiwavelength picosecond optical pulses. This method is based on chirp compression of phase-modulated light, followed by nonlinear pulse compression and reshaping with a double-side Mamyshev reshaper. We show that this method becomes power efficient when the repetition rate is increased to 25 GHz. Wavelength-tunable optical pulses with a repetition rate of 25 GHz and pulse width of ∼2  ps, which can be temporally multiplexed to 100 GHz, are experimentally obtained over a large spectral range with moderate electrical and optical power. Simultaneous pulse generation on four wavelengths is demonstrated.
