This work introduces a new class of PT-symmetry grating assisted devices for switching or modulation applications. Their operation is based on a four-wave interaction, thus marking a step forward in the development of PT-symmetry devices which currently are essentially based on two-wave interactions...

Physically, PT -symmetry requirements can be easily understood by using the system of two linearly coupled oscillators20,22 (dimers, or waveguides in photonics ). The system obeys PT -symmetry criteria if the rate of dissi- pation for one of the oscillators is exactly equal to the rate of ...

Parity-time (PT) symmetry and broken in micro-/nanophotonic structures have been investigated extensively as they bring new opportunities to control the fl
PT-symmetryIn recent years, the concept of parity-time (PT) symmetry has received considerable attention in the field of optics and photonics. In PT-symmetric arrangements, the interaction between gain/loss-contrast and coupling leads to the formation of exceptional points in parameter space. At ...
In the next section, we use a concrete example to show that when parity () and time-reversal ( ) symmetries are broken but PT symmetry is not broken, the spatial symmetry of the scattered waves can be nearly opposite to that of the excitation plane wave, which finally gives rise...
