Hybrid silicon all-optical switching devices integrated with two-dimensional material
Daiki Yamashita, Nan Fang, Shun Fujii +1
We propose and demonstrate hybrid all-optical switching devices that combine silicon nanocavities and two-dimensional semiconductor material. By exploiting the refractive index mod…
