Supercontinuum generation from Topological Edge Supermodes in a short SSH Photonic Crystal Fiber

Daniel Rodriguez-Guillen, Carlos Wiechers, Lorena Velazquez-Ibarra

We introduce a topological photonic-crystal fiber that embeds a short Su-Schrieffer-Heeger (SSH) chain and supports two edge supermodes. Using full-vector modal analysis and a coup…
