“…The question still lingers: do the results obtained above truly hinge on the presence of gain in the system? It has been demonstrated that a modulation of lossy components can be used to obtain some non-Hermitian features involving light propagation [8,21,[31][32][33]. This represents a major advance in view of technological applications because introducing loss in a system is much easier than dealing with active components.…”

The polarization matrix formalism is employed to analyze the polarization properties of transmitted narrowband light through several optical setups involving active and dissipative structures. It is demonstrated that the degree of polarization of the output light can increase after propagation in a active/dissipative periodic media. Furthermore, the impact of introducing optical elements like polarizers, compensators, and rotators is examined, and their collective effect on the degree of polarization is discussed.

“…A few papers have been published exploring the role of second-order classical coherence in non-Hermitian systems [20][21][22][23][24][25][26][27][28][29]. So far, only scattering and paraxial beam propagation have been considered and the role of spatial coherence in non-Hermitian system was explored.…”

The propagation of a Gaussian–Schell beam through a PT-symmetric optical lattice, whose index of refraction is represented by a sinusoidal type of function, is theoretically investigated. Within the framework of standard coherence theory, one is able to access and elucidate unexpected consequences of the interplay between the spatial coherence properties of the beam and the non-Hermitian nature of the photonic lattice. We describe how one may use a non-Hermitian periodic medium to enhance the spatial coherence properties of a partially coherent beam.
