Abstract

We consider a PT-symmetric laser system comprising active and passive (lossy) coupled micro-resonators. It is shown that at its exceptional point (EP), the system satisfies the white light cavity (WLC) condition, exhibiting zero group index Slightly above lasing threshold, in the broken symmetry regime near the EP, the system exhibits "superluminal" lasing. It is also shown that some of the latest experimental studies involving PTSSs have indirectly demonstrated such superluminal lasing.
