This paper proposes XPM-induced noise mitigation by gain saturated parametric amplifiers to improve signal-to-noise ratio (SNR)in coherent WDM fiber transmission systems. We employ semi-analytical scheme to estimate the SNR considering the XPM-induced phase noise.

We demonstrate a narrow-band telecom two-photon source for long-distance quantum communication. The second-order cross-correlation function reveals narrow linewidth of 2.4 MHz and the highest spectral brightness of3.94 × 105 pairs/(s.MHz.mW).

The femtosecond laser-induced periodic surface structure (FLIPSS) is a one-step process for fast fabrication of periodic-like nanostructures on different materials and enables a new range of functionalized surface processing [1]. In our pervious study, ablation of a copper foil surface by femtosecond laser pulse (800 nm, 120 fs) was investigated theoretically and experimentally [2]. The simulated ablation depths agree well with the experimental measurements.

With the assistance of optical time-stretch using the lately developed free-space angular-chirp-enhanced delay cavity, we demonstrate the short pulse generation numerically by passively mode-locking a fiber optical parametric oscillator pumped by a quasi-CW pump.
