Observation of stability of Gaussian beams and off-axis beam-cleaning in graded-index media

Varun Sharma, Nicholas Bender, Henry Haig +3

While nonlinear effects in graded-index (GRIN) multimode fibers have been studied extensively, little is known about nonlinear effects in larger GRIN waveguides, where the number o…

Experimental observation of a photonic hook

Igor V. Minin, Oleg V. Minin, Gleb M. Katyba +6

In this letter, we report the first experimental observation of a photonic hook - a new type of near field curved light generated at the output of dielectric cuboid with broken sym…

Fluctuations and noise-limited sensing near the exceptional point of -symmetric resonator systems

N. Asger Mortensen, P. A. D. Gonçalves, Mercedeh Khajavikhan +3

We theoretically explore the role of mesoscopic fluctuations and noise on the spectral and temporal properties of systems of -symmetric coupled gain-loss resonators o…

Multimode Nonlinear Fiber Optics: Massively Parallel Numerical Solver, Tutorial and Outlook

Logan G. Wright, Zachary M. Ziegler, Pavel M. Lushnikov +4

Building on the scientific understanding and technological infrastructure of single-mode fibers, multimode fibers are being explored as a means of adding new degrees of freedom to…

Interferometric control of the photon-number distribution

H. Esat Kondakci, Alexander Szameit, Ayman F. Abouraddy +2

We demonstrate deterministic control over the photon-number distribution by interfering two coherent beams within a disordered photonic lattice. By sweeping a relative phase betwee…

PT-symmetric transport in non-PT-symmetric bi-layer optical arrays

J. Ramirez-Hernandez, F. M. Izrailev, N. M. Makarov +1

We study transport properties of an array created by alternating layers with balanced loss/gain characterized by the key parameter . It is shown that for non-equal width…

Light transport in PT-invariant photonic structures with hidden symmetries

M. H. Teimourpour, R. El-Ganainy, A. Eisfeld +2

We introduce a recursive bosonic quantization technique for generating classical PT photonic structures that possess hidden symmetries and higher order exceptional points. We study…

Ermakov-Lewis symmetry in photonic lattices

B. M. Rodríguez Lara, P. Aleahmad, H. M. Moya-Cessa +1

We present a class of waveguide arrays that is the classical analog of a quantum harmonic oscillator where the mass and frequency depend on the propagation distance. In these photo…

Optical Asymmetry Induced by PT-symmetric Nonlinear Fano Resonances

F. Nazari, N. Bender, H. Ramezani +3

We introduce a new type of Fano resonances, realized in a photonic circuit which consists of two nonlinear PT-symmetric micro-resonators side-coupled to a waveguide, which have lin…

Observation of Asymmetric Transport in Structures with Active Nonlinearities

N. Bender, S. Factor, J. D. Bodyfelt +3

A mechanism for asymmetric transport based on the interplay between the fundamental symmetries of parity (P) and time (T) with nonlinearity is presented. We experimentally demonstr…

Unidirectional Nonlinear PT-symmetric Optical Structures

Hamidreza Ramezani, Tsampikos Kottos, Ramy El-Ganainy +1

We show that non-linear optical structures involving a balanced gain-loss profile, can act as unidirectional optical valves. This is made possible by exploiting the interplay betwe…

Nonlinear Femtosecond Pulse Reshaping in Waveguide Arrays

Darren D. Hudson, Kimberlee Shish, Thomas R. Schibli +4

We observe nonlinear pulse reshaping of femtosecond pulses in a waveguide array due to coupling between waveguides. Amplified pulses from a mode-locked fiber laser are coupled to a…
