Tunable all-dielectric metasurface for phase modulation of the reflected and transmitted light via permittivity tuning of indium tin oxide

Autor: Forouzmand Ali, Salary Mohammad Mahdi, Kafaie Shirmanesh Ghazaleh, Sokhoyan Ruzan, Atwater Harry A., Mosallaei Hossein

Publikováno v: Nanophotonics, Vol 8, Iss 3, Pp 415-427 (2019)

We propose an electrically tunable metasurface, which can achieve relatively large phase modulation in both reflection and transmission modes (dual-mode operation). By integration of an ultrathin layer of indium tin oxide (ITO) as an electro-opticall

Subwavelength Silicon Nanoblocks for Directional Emission Manipulation

Autor: Tianyue Zhang, Xuewei Li, Jian Xu, Xiaoming Zhang, Zi-Lan Deng, Xiangping Li

Publikováno v: Nanomaterials, Vol 10, Iss 6, p 1242 (2020)

Manipulating the light emission direction and boosting its directivity have essential importance in integrated nanophotonic devices. Here, we theoretically propose a single dielectric silicon nanoblock as an efficient, multifunctional and ultracompac

Optical Yagi-Uda nanoantennas

Autor: Maksymov Ivan S., Staude Isabelle, Miroshnichenko Andrey E., Kivshar Yuri S.

Publikováno v: Nanophotonics, Vol 1, Iss 1, Pp 65-81 (2012)

Conventional antennas, which are widely employed to transmit radio and TV signals, can be used at optical frequencies as long as they are shrunk to nanometer-size dimensions. Optical nanoantennas made of metallic or high-permittivity dielectric nanop
