# Frequency comb generation through the locking of domain walls in doubly resonant dispersive optical parametric oscillators

## TL;DR

This paper theoretically explores how domain wall locking in doubly resonant dispersive optical parametric oscillators enables the formation of stable, localized frequency combs, advancing understanding of nonlinear optical dynamics.

## Contribution

It introduces a nonlocal mean field model demonstrating that domain wall locking can produce stable optical frequency combs in these oscillators.

## Key findings

- Domain wall locking leads to stable frequency combs.
- A nonlocal mean field model is derived.
- Stable coherent combs are achievable in the system.

## Abstract

In this letter we theoretically investigate the formation of localized temporal dissipative structures, and their corresponding frequency combs in doubly resonant dispersive optical parametric oscillators. We derive a nonlocal mean field model, and show that domain wall locking allows for the formation of stable coherent optical frequency combs.
