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…
