Optical rogue waves in multifractal photonic arrays
Optical rogue waves are demonstrated in the far field scattered radiation from photonic arrays designed according to the aperiodic distributions of prime elements in complex quadratic fields. Specifically, by studying light diffraction from Eisenstein and Gaussian prime arrays we establish a connection between the formation of optical rogue waves and multifractality in the visible regime. We link strong multifractality with the heavy tail probability distributions that describe the fluctuations of scattered radiation from the fabricated arrays. Our findings pave the way to control high intensity rogue waves using deterministic arrays of dielectric nanostructures for enhanced sensing and lithographic applications.
