Experimental realization of wide-mode-area slow light modes in valley photonic crystal heterostructure waveguides
Chengkun Zhang, Guangtai Lu, Nattujuks Pholsen +2
We experimentally realized wide-mode-area slow-light modes in valley photonic crystals (VPhCs) heterostructure waveguides. The waveguides are fabricated on a silicon slab by insert…
