Title: Time-domain measurement of ultra-fast intensity difference squeezed pulse pairs generated in fiber
Authors: Wen Zhao, Xueshi Guo and Xiaoying Li
Abstract summary: Pulsed pumped four-wave mixing process via $chi(3)$ non-linearity in optical fiber can generate optical pulses with continuous variable quantum correlation. We show the generated twin-beam pulses are pair-wisely correlated, and -3.8 dB (-8.1 dB after detection losses correction) intensity difference squeezing degree is measured in time-domain.

Abstract: Pulsed pumped four-wave mixing process via $\chi^{(3)}$ non-linearity in optical fiber can generate optical pulses with continuous variable quantum correlation. However, pair-wise correlation of the generated pulses in this system has not been studied. Here we report a time-domain measurement of an intensity difference squeezed state generated in fiber. With a fast response differential detection system, we show the generated twin-beam pulses are pair-wisely correlated, and -3.8 dB (-8.1 dB after detection losses correction) intensity difference squeezing degree is measured in time-domain. Our result is benefit for generating multi-mode entangled state by time-division multiplexing in fiber system.

Observation of binary phase states of time-multiplexed degenerate optical parametric oscillator pulses generated using a nonlinear fiber Sagnac loop [0.0]
We generated more than 5,000 time-multiplexed DOPO pulses using a nonlinear fiber Sagnac loop as a phase-sensitive amplifier. We confirmed the bifurcation of pulse phases to 0 or $pi$ relative to the pump phase, which makes them useful for representing Ising spins in an Ising model solver.

We report the experimental realisation of an optical fractional Schr"odinger equation (FSE) for femtosecond laser pulses in the temporal domain. The temporal dynamics is observed in diverse forms, including solitary, splitting and merging pulses, double Airy modes, and rain-like'' multi-pulse patterns. The experimentally generated fractional time-domain pulses offer the potential for designing optical signal-processing schemes.

We performed theoretical analysis of the phase randomness in a gain-switched semiconductor laser in the context of its application as a quantum entropy source. Numerical simulations demonstrate that phase diffusion r.m.s. exhibits non-linear dependence on the bias current. It is shown that phase diffusion between laser pulses cannot always be assumed to exhibit required efficiency.
