Effect of synchronous regeneration on the soliton optical phase

Olivier Leclerc, E. Desurvire

Published Nov 27, 2002• 0 citations

Abstract

We show that soliton regeneration reduces both amplitude and optical phase noise in a squeezing-like fashion. However, control of optical phase is found not sufficient to permit error-free phase-coded soliton transmission. In order to investigate the impact of soliton regeneration on both amplitude and phase noise, we calculated the evolution of these characteristics along the system.

Effect of synchronous modulation on the soliton optical phase

Olivier Leclerc, E. Desurvire

We show that soliton regeneration through synchronous modulation reduces both amplitude and optical phase noise in a squeezinglike fashion. However, control of optical phase noise is found not to be sufficient to permit error-free phase-shift-keyed soliton transmission, as confirmed by numerical simulations.

Noise effects on the transmission of optical solitons

J. P. Gordon

I will discuss the limits imposed by noise on the long-distance transmission of information via optical solitons. Phase noise prohibits the use of phase sensitive systems. Amplitude (energy) noise and timing noise (the Gordon-Haus effect) yield limitations on the information rate. The recent idea of soliton guiding using filters in the line reduces the soliton fluctuations at the expense of increased background noise.

Phase noise squeezing without PM-to-AM conversion by hybrid optical phase squeezer

Takayuki Kurosu, Hung Nguyen Tan, Karen Solis-Trapala +1 more

We demonstrate, for the first time, phase regeneration of BPSK signals without phase-to-amplitude noise conversion using a hybrid optical phase squeezer. Improvement over the conventional method was confirmed through an error vector magnitude reduction.

Phase-noise scaling in quantum soliton propagation

Robert M. Shelby, P. D. Drummond, S. J. Carter

We treat the scaling of thermal phase-noise effects and quantum fluctuations for solitons in optical fibers. The central result is that the size of the thermal noise relative to quantum noise is reduced in proportion to the soliton duration for solitons whose duration is less than the thermal correlation times, suggesting that squeezed quantum solitons should be realizable in optical fibers. The physical basis for this effect is largely the fact that squeezing, which is nonlinear, occurs more rapidly for shorter pulses.

Squeezing of optical solitons

Robert M. Shelby, M. Rosenbluh

Optical solitons are pulses that propagate in optical fibers without temporal or spectral distortion, owing to balancing of the second-order dispersion of the refractive index by nonlinear self-phase modulation induced by the intensity-dependent refractive index. Classically, this stationary, distortion-free propagation requires only the proper choice of pulse width and shape for a given pulse energy. However, quantum mechanical zero-point fluctuations of the amplitude and phase of the optical pulse limit the precision with which this pulse shape can be produced. These quantum fluctuations do not undergo stationary propagation but, rather, evolve because of dispersion and self-phase modulation, As a soliton pulse propagates, this zero-point or vacuum noise associated with the pulse evolves into squeezed noise owing to self-phase modulation in the fiber.1,2

Investigation of an All-Optical Black-Box PPLN-PPLN BPSK Phase Regenerator

A. Szabo, Benjamin James Puttnam, Dániel Mazroa +2 more

We investigate the phase squeezing performance of an all-optical black-box binary phase-shift keyed phase regenerator constructed from periodically-poled lithium-niobate (PPLN) waveguides. Phase regeneration is performed with different levels of phase noise and constant amplitude noise added to the phase modulated input. We experimentally show that, for moderate phase noise, unwanted phase-to-amplitude noise conversion can be minimized without degradation of the phase squeezing performance, by controlling the signal-to-pump power ratio at the input to the PPLN-based phase-sensitive regenerator.
