On-chip channelless diffraction-free beam guiding enables dense integration of optical
circuits in a reconfigurable manner, where total internal reflection, which is considered the …

Parity-time (PT) symmetric coupled resonator systems have exhibited intriguing and
unexpected properties in optics and electronics. Here, we extend it to acoustics and report a …

This work demonstrates how the crystal symmetry of photonic crystal defect waveguides
interacts with simple, experimentally realizable parity-time (\calP\calT PT) symmetric regions …

An analytical approximation for the eigenvalues of PT-symmetric Hamiltonian H=− d 2/dx
2−(ix) ε+ 2, ε>− 1 is developed via simple basis sets of harmonic-oscillator wave functions …

We analyze self-collimation in two-dimensional periodic complex lattices. We consider P-
symmetric and PT-symmetric complex lattices with different geometries, where the periodic …

We propose a method to control turbulence by the introduction a non-Hermitian
spatiotemporal modulation, based on the energy redirection from unstable to stable modes …

Recent advancement in Photonics have brought about a new era of miniaturisation. Along
came a need for technology to allow the manipulation of light at the micrometer scale, with …
