Adiabatons in a double tripod coherent atom-light coupling scheme

TL;DR

This paper investigates the formation of optical adiabatons in complex atomic systems, demonstrating that double tripod configurations support stable shape-invariant pulses, unlike M-type systems which face propagation issues.

Contribution

It provides the first analysis of adiabaton formation in double tripod atomic systems, highlighting their suitability for stable optical pulse propagation.

Findings

Double tripod systems support shape-invariant optical adiabatons.

M-type systems exhibit intensity-dependent group velocity and pulse steepening.

Double tripod configurations enable two different stable optical field profiles.

Abstract

Optical adiabatons are specific shape-invariant pulse pairs propagating at the reduced group velocity and without optical absorption in the medium. The purpose of this study is to analyze and demonstrate adiabaton formation in many level atomic systems. Here we focus on the analysis of five level M-type and double tripod systems. It is found that M-type atomic systems are prone to intensity dependent group velocity and pulse front steepening which prevents the formation of long range optical adiabatons. In contrast, the double tripod atomic system is quite favorable for the formation of optical adiabatons leading to two different optical field configurations propagating with invariant shape.
