Soliton-guided phase shifter and beam splitter

Abstract

We propose, analyze, and study numerically a phase shifter for light wave packets trapped by Kerr solitons in a nonlinear medium. We also study numerically a previously proposed soliton-guided nonpolarizing beam splitter.

Induced soliton ejection from a continuous-wave source waveguided by an optical pulse soliton train

“…The induced-phase-modulation (or cross-phase-modulation) process has been predicted two decades ago [1,2,9,10], and experimentally observed [3,4] to occur when a lowpower signal (either an harmonic cw signal or a weakly nonlinear signal) couples to a high-intensity pump signal, the later one providing an optical waveguiding structure and reshaping channel to the first for substantial increase of its lifetime. However while this process is rather well understood for single-soliton pumps and in the case of relatively weak cross-phase-modulation processes, almost no insight exists about the context of pump signals consisting of periodic networks of temporal or spatial solitons [18].…”

“…Since this key input as well as the subsequent experimental evidences reported in [3,4] it has become evident that besides their most common applications in long-distance transmission of high-power signals [5,6], solitons could be prime candidates for controlling light by light [7,8]. More advanced studies have been carried out in recent years based on numerical simulations, and revealed that due to their unique stability properties solitons provide excellent and reliable guiding structures for reconfigurable low-power signals and re-routinable high-power pulses [9,10]. Particularly attracting is the possibility to construct soliton networks that can be used as nonlinear waveguide arrays, as established in the landscape of recent experiments [11,12,13,14,15,16] emphasizing the outstanding robustness of the periodic lattices of optical solitons with flexible (hence controllable) refractive index modulation depth and period that are induced all-optically.…”

“…Given the tunable character of the effective refractive index as well as the flexible modulation period, a great number of new opportunities for all-optical manipulation of light can be envisaged since in this case, periodic optical-soliton waveguides can operate in both weak and strong-coupling regimes depending on the depth of refractive index modulation. Transmission techniques exploiting optically-induced waveguiding configurations with solitons are now common in several communication media such as laser [17], photon [9,10,18] systems and photorefractive semiconductor [19] media. The present work aims at extending the phenomenon of signal reconfiguration by strong optical fields to the context of an harmonic cw beam trapped in the guiding structure of a periodic pulse train.…”

An Analytical Scheme for the Analysis of Multi-Hump Solitons

“…It is proven in the seminal paper by Knill et al that it is possible to implement general quantum computing using only beam-splitters, phase-shifters, single-photon sources and photo-detectors [10]. In a series of papers [21][22][23], Steiglitz has demonstrated that the scheme proposed by Knill et al scheme can be realized using soliton-guided photons.…”

Novel asymmetric representation method for solving the higher-order Ginzburg-Landau equation

“…Optical solitons can maintain their shapes and velocities during their propagation under the balance between group-velocity dispersion (GVD) and Kerr nonlinearity 4 . By virtue of the advantage of shape preserving, optical solitons have been applied in the optical switching, phase shifter, amplifier, and information storage 5 6 7 8 .…”
