Autor: Min Taeyol, Yim Jong Hyuk, Park Sungmin, Ha Seongju, Lee Soonil, Yeom Dong-Il

Publikováno v: Nanophotonics, Vol 12, Iss 1, Pp 71-79 (2022)

A randomly connected single-walled carbon nanotube (CNT) network film is suggested as an optically homogenous thin film to implement a tunable diffractive optical element with a subwavelength thickness. A Fresnel zone plate (FZP) as a thin-film lens

Strong electro-optic absorption spanning nearly two octaves in an all-fiber graphene device

Autor: Park Nam Hun, Ha Seongju, Chae Kwanbyung, Park Ji-Yong, Yeom Dong-Il

Publikováno v: Nanophotonics, Vol 9, Iss 15, Pp 4539-4544 (2020)

An efficient electro-optic transition control is reported in all-fiber graphene devices over a broad spectral range from visible to near-infrared. The ion liquid–based gating device fabricated onto a side-polished fiber with high numerical aperture
