Abstract

Using numerical simulations of the Maxwell-Bloch equations, PT-symmetry breaking is investigated in onedimensional structures with resonantly absorbing and amplifying layers. We reveal the lasing-like regime and saturation of loss and gain above the exceptional point. The uniqueness of phase transition due to saturation and the direction locking of the transmitted and reflected radiation in the lasing-like regime are predicted.
