Nonlocal effects in waveguide arrays with PT-symmetric defects

Dmitriev, Sergey V; Suchkov, Sergey V; Sukhorukov, Andrey; Kivshar, Yuri


Photonic structures composed of coupled waveguides with loss and gain regions offer new possibilities for shaping optical beams and pulses compared to conservative structures [1, 2]. Such structures can be designed as optical analogues of complex parity-time (or PT) symmetric potentials, which can have a real spectrum corresponding to the conservation of power for optical eigenmodes, for the magnitude of gain/loss below a certain threshold. When gain/loss is increased above the threshold, PT...[Show more]
