The Lugiato-Lefever equation driven by a double tightly focused pump
Mateus C. P. dos Santos, Shatrughna Kumar, Wesley B. Cardoso +1
We introduce a model of an optical cavity based on the one-dimensional Lugiato-Lefever (LL) equation, which includes the pump represented by a symmetric pair of tightly localized "…

Stable patterns in the Lugiato-Lefever equation with a confined vortex pump
Shatrughna Kumar, Wesley B. Cardoso, Boris A. Malomed
We introduce a model of a passive optical cavity based on a novel variety of the two-dimensional Lugiato-Lefever equation, with a localized pump carrying intrinsic vorticity S, and…
