Coexistence of a new type of bound state in the continuum and a lasing threshold mode induced by PT symmetry

Some photonic systems support bound states in the continuum (BICs) that have infinite lifetimes, although their frequencies and momenta are matched to vacuum modes. Using a prototypical system that can be treated analytically, we show that each of these BICs always splits into a pair of new type BIC...
