Hybrid guided space-time modes with controllable group indices in a multi-mode planar waveguide

Abbas Shiri and Ayman F. Abouraddy

Not Accessible

Your library or personal account may give you access

Abstract

In a multi-mode waveguide, higher-order modes are usually slower than lower-order modes. We circumvent this limitation and demonstrate anomalous group-index behavior using space-time wave packets in a 4-microns-thick multi-mode planar waveguide.
