Generation of ring-shaped optical vortices in dissipative media by inhomogeneous effective diffusion
Shiquan Lai, Huishan Li, Yunli Qui +4
By means of systematic simulations we demonstrate generation of a variety of ring-shaped optical vortices (OVs) from a two-dimensional input with embedded vorticity, in a dissipati…

Pinned modes in lossy lattices with local gain and nonlinearity
Boris A. Malomed, Edwin Ding, K. W. Chow +1
We introduce a discrete linear lossy system with an embedded "hot spot" (HS), i.e., a site carrying linear gain and complex cubic nonlinearity. The system can be used to model an a…
