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…

Wide-mode-area slow light waveguides in valley photonic crystal heterostructures
Chengkun Zhang, Yasutomo Ota, Satoshi Iwamoto
We designed slow-light waveguides with a wide mode area based on slab-type valley photonic crystal (VPhC) heterostructures which are composed of a graphene-like PhC sandwiched by t…
