Optical solitons and stability analysis with coupled nonlinear schrodinger’s equations having double external potentials

Results in Physics, 2019
We consider coupled nonlinear Schrodinger equation (CNLSE) of the Gross-Pitaevskii-type, with linear mixing and nonlinear cross-phase modulation. Motivated by the study of matter waves in Bose-Einstein condensates and multicomponent (vectorial) nonlinear

Filtration mapping as complete Bell state analyzer for bosonic particles

Scientific Reports, 2021
In this paper, we present the approach to complete Bell state analysis based on filtering mapping. The key distinctive feature of this appoach is that it avoids complications related to using either hyperentanglement or representation of the Bell states ...

Spatially structured multi-wave-mixing induced nonlinear absorption and gain in a semiconductor quantum well

Scientific Reports, 2022
We have studied two-dimensional absorption and gain spectrum in an asymmetric semiconductor triple-coupled-quantum-well (TCQW) nanostructure. Four subband transitions are coupled by using four coherent fields in a close-loop configuration to introduce ...

Polarization Rotation in Silicon Waveguides: Analytical Modeling and Applications

IEEE Photonics Journal, 2010
The efficient use of optical nonlinearities in silicon is crucial for the implementation of silicon-based photonic devises. In this paper, we present an approximate analytical study of nonlinear polarization rotation in silicon-on-insulator (SOI ...

Kerr non-linearity in a superconducting Josephson metamaterial

, 2018
We present a detailed experimental and theoretical analysis of the dispersion and non-linear Kerr frequency shifts of plasma modes in a one-dimensional Josephson junction chain containing 500 SQUIDs in the regime of weak nonlinearity.

The phase of darkness – measuring the phase of a dark pulse [PDF]

EPJ Web of Conferences
Dark optical solitons are solutions to the nonlinear Schrödinger equation in normal dispersion media with positive Kerr nonlinearity, exhibiting a discrete π phase jump. These solitons are valuable to applications within telecommunication.

Josephson junction-embedded transmission-line resonators: from Kerr medium to in-line transmon

, 2012
We provide a general method to find the Hamiltonian of a linear circuit in the presence of a nonlinearity. Focussing on the case of a Josephson junction embedded in a transmission-line resonator, we solve for the normal modes of the system by taking into

Quantum computation using weak nonlinearities: robustness against decoherence [PDF]

, 2006
We investigate decoherence effects in the recently suggested quantum computation scheme using weak nonlinearities, strong probe coherent fields, detection and feedforward methods. It is shown that in the weak-nonlinearity-based quantum gates, decoherence

Intracavity weak nonlinear phase shifts with single photon driving

, 2009
We investigate a doubly resonant optical cavity containing a Kerr nonlinear medium that couples two modes by a cross phase modulation. One of these modes is driven by a single photon pulsed field, and the other mode is driven by a coherent state. We find
