Higher Order Mode Supercontinuum Generation Through Nano-Printed Meta-Fiber — •Shahrzad Hosseinabadi, Mohammadhossein Khosravi, Matthias Zeisberger, Torsten Wieduwilt, and Markus Schmidt — Leibniz Institute of Photonic Technology, Jena, Germany

Optical fibers, with their unique light guiding properties, have transformed modern society. Besides the common fundamental mode, fibers also support higher-order modes (HOMs), gaining attention for different applications. In nonlinear frequency conversion research, HOMs play a crucial role, offering access to unique dispersion landscapes. This enables applications such as broadband supercontinuum generation and exploration of novel nonlinear effects. However, efficiently exciting or converting HOMs poses a challenge due to the need for precise matching of modal properties, especially in nonlinear photonics. Current approaches, like spatial light modulators and waveplates, have limitations such as being costly, poorly integrated, and require extensive computer control and additional alignment. We explore the use of dielectric nanostructures specifically holograms and metasurfaces for advanced beam shaping with minimal losses. Our study specifically investigates the efficient utilization of HOMs in nonlinear optical fibers. Leveraging diffractive lenses technology, we aim to enhance HOMs' performance, proposing a compact integrated device for nonlinear photonics applications.
