Edge-Mode Lasing in 1D Topological Active Arrays.
We report the first observation of lasing topological edge states in a 1D Su-Schrieffer-Heeger active array of microring resonators. We show that the judicious use of non-Hermiticity can promoteExpand

High-density waveguide superlattices with low crosstalk.
Silicon photonics holds great promise for low-cost large-scale photonic integration. In its future development, integration density will play an ever-increasing role in a way similar to thatExpand

Bessel X waves in two- and three-dimensional bidispersive optical systems.
We show that new families of two- and three-dimensional nondiffracting Bessel X waves are possible in linear bidispersive optical systems. These X waves can be observed in both bulk and waveguideExpand

Spatiotemporal mode-locking in multimode fiber lasers
Harnessing complexity in laser light The development of lasers and the quality of the output light has been crucially dependent on understanding and being able to control the process occurring withinExpand

Supersymmetric optical structures.
We show that supersymmetry can provide a versatile platform in synthesizing a new class of optical structures with desired properties and functionalities. By exploiting the intimate relationshipExpand

Supersymmetric mode converters
We present the first experimental realization of optical supersymmetry and demonstrate mode conversion and global phase-matching between SUSY partner structures. Our results may pave the way forExpand

Continuous and discrete Schrödinger systems with parity-time-symmetric nonlinearities.
We investigate the dynamical behavior of continuous and discrete Schrödinger systems exhibiting parity-time (PT) invariant nonlinearities. We show that such equations behave in a fundamentallyExpand

Implementation of quantum and classical discrete fractional Fourier transforms
TLDR
We report classical and quantum optical realizations of the discrete fractional Fourier transform of exemplary wave functions and experimentally demonstrate the shift theorem. Expand
