Cavity Soliton Laser based on mutually coupled semiconductor microresonators

TL;DR

This paper reports the experimental discovery of cavity solitons in mutually coupled semiconductor microresonators, which can be individually controlled without external driving beams, advancing the understanding of localized laser structures.

Contribution

It demonstrates the existence and controllability of cavity solitons in coupled microresonators without external driving, a novel experimental observation.

Findings

Localized structures coexist with dark background

Cavity solitons can be switched on and off individually

Structures do not require external driving beams

Abstract

We report on experimental observation of localized structures in two mutually coupled broad-areahttp://hal.archives-ouvertes.fr/images/calendar.gif semiconductor resonators. These structures coexist with a dark homogeneous background and they have the same properties as cavity solitons without requiring the presence of a driving beam into the system. They can be switched individually on and off by means of a local addressing beam.
