Abstract

We show that parity-time- ($\mathcal{PT}$-) symmetric coupled optical waveguides with gain and loss support localized oscillatory structures similar to the breathers of the classical ${\ensuremath{\phi}}^{4}$ model. The power carried by the $\mathcal{P}\mathcal{T}$ breather oscillates periodically, ...
