Findings

Scar modes can be selectively amplified by positioning gain near specific orbit points.

Numerical simulations confirm the effectiveness of the proposed amplification mechanism.

The method enables control over mode amplification in complex optical fibers.

Abstract

In this letter we propose an original mechanism to select scar modes through coherent gain amplification in a multimode D-shaped fiber. More precisely, we numerically demonstrate how scar modes can be amplified by positioning a gain region in the vicinity of specific points of a short periodic orbit known to give rise to scar modes.
