TL;DR
This paper investigates how field diffusion affects cavity solitons in bidirectional lasers, demonstrating that diffusion enhances their stability and reduces interactions, enabling independent control of solitons.
Contribution
It reveals the dual role of diffusion in stabilizing cavity solitons and reducing their interactions, facilitating individual manipulation.
Findings
Diffusion increases the stability range of cavity solitons.
Diffusion reduces long-range interactions between solitons.
Enables independent writing and erasing of solitons.
Abstract
We study the influence of field diffusion on the spatial localized structures (cavity solitons) recently predicted in bidirectional lasers. We find twofold positive role of the diffusion: 1) it increases the stability range of the individual (isolated) solitons; 2) it reduces the long-range interaction between the cavity solitons. Latter allows the independent manipulation (writing and erasing) of individual cavity solitons.
