TL;DR

This paper explores the properties and control mechanisms of gap solitons in a resonant photonic crystal, demonstrating how modulation can manipulate soliton behavior and operational regimes.

Contribution

It introduces a novel analysis of oscillating gap solitons in resonant photonic crystals, highlighting control strategies via modulation parameters.

Findings

Oscillating gap solitons can be manipulated by bit rate, phase, and amplitude modulation.

Effective control requires delay time and amplitude difference to exceed certain thresholds.

Different operational regimes of the photonic crystal are identified and explained.

Abstract

We demonstrate interesting and previously unforeseen properties of a pair of gap solitons in a resonant photonic crystal which are predicted and explained in a physically transparent form using both analytical and numerical methods. The most important result is the fact that an oscillating gap soliton created by the presence of a localized population inversion inside the crystal can be manipulated by means of a proper choice of bit rate, phase and amplitude modulation. Developing this idea, we are able to obtain qualitatively different regimes of a resonant photonic crystal operation. In particular, a noteworthy observation is that both the delay time and amplitude difference must exceed a certain level to ensure effective control over the soliton dynamics.
