Seunghoon Lee,Muhan Choi,Muhan Choi,Teun-Teun Kim,Teun-Teun Kim,Seungwoo Lee,Ming Liu,Xiaobo Yin,Hongkyw Choi,Seung S. Lee,Choon-Gi Choi,Sung-Yool Choi,Xiang Zhang,Xiang Zhang,Bumki Min +14 more
TL;DR: It is demonstrated that substantial gate-induced persistent switching and linear modulation of terahertz waves can be achieved in a two-dimensional metamaterial, into which an atomically thin, gated two- dimensional graphene layer is integrated.
Journal ArticleDOI

Muhan Choi,Seunghoon Lee,Yushin Kim,Seung Beom Kang,Jonghwa Shin,Min Hwan Kwak,Kwang-Young Kang,Yong-Hee Lee,Namkyoo Park,Bumki Min +9 more
TL;DR: It is demonstrated that a broadband, extremely high index of refraction can be realized from large-area, free-standing, flexible terahertz metamaterials composed of strongly coupled unit cells.

Seunghoon Lee,Muhan Choi,Teun-Teun Kim,Seungwoo Lee,Ming Liu,Xiaobo Yin,Hongkyw Choi,Seung S. Lee,Choon-Gi Choi,Sung-Yool Choi,Xiang Zhang,Bumki Min +11 more
TL;DR: In this paper, the gate-induced persistent switching and linear modulation of terahertz waves can be achieved in a two-dimensional artificial material, referred to as a metamaterial, into which an atomically thin, gated twodimensional graphene layer is integrated.
Journal ArticleDOI
High- Q surface-plasmon-polariton whispering-gallery microcavity
Bumki Min,Bumki Min,Bumki Min,Eric Ostby,Volker J. Sorger,Erick Ulin-Avila,Lan Yang,Lan Yang,Xiang Zhang,Xiang Zhang,Kerry J. Vahala +10 more
TL;DR: A high-Q SPP whispering-gallery microcavity that is made by coating the surface of a high- Q silica microresonator with a thin layer of a noble metal is demonstrated and Q factors of 1,376 ± 65 can be achieved in the near infrared for surface-plasmonic whispering- gallery modes at room temperature.
Journal ArticleDOI
Ultralow-threshold erbium-implanted toroidal microlaser on silicon
TL;DR: In this article, an erbium-doped microlaser on silicon operating at a wavelength of 1.5 µm was presented, with an average Er concentration of 2x10^(19) cm(-3).
