A Band-Switchable and Tunable THz Metamaterial Based on an Etched Vanadium Dioxide Thin Film
Autor: Jun-Hwan Shin, Kyung Hyun Park, Han-Cheol Ryu
Publikováno v: Photonics, Vol 9, Iss 2, p 89 (2022)
A band-switchable and tunable terahertz (THz) metamaterial based on a vanadium dioxide (VO2) thin film was proposed in the THz frequency regime. The VO2 thin film with a high conductivity change rate and smooth phase transition characteristics was de

Investigations on Practical Issues in Solid Immersion Lens Based Sub-Wavelength Terahertz Imaging Technique: System Stability Verification and Interference Pattern Removal
Autor: Da-Hye Choi, Jun-Hwan Shin, Il-Min Lee, Kyung Hyun Park
Publikováno v: Sensors, Vol 21, Iss 21, p 6990 (2021)
Terahertz (THz) imaging techniques are attractive for a wide range of applications, such as non-destructive testing, biological sensing, and security imaging. We investigate practical issues in THz imaging systems based on a solid immersion lens (SIL

Atmospheric vapor-transport method for growth of VO2 single-crystalline nano- and microwires
Autor: Jun-Hwan Shin, Tetiana Slusar, Hyun-Tak Kim, Jin Chul Cho, Bong-Jun Kim
Publikováno v: Journal of the Korean Physical Society. 78:6-10
The growth of high-quality single crystalline nano- and microwires of VO2 is necessary to study the Mott transition and to expand its applications. Here, we propose a modified vapor-transport method characterized by a one-step process that does not r

Photonics-Based 300 GHz Band Wireless Terahertz Link using 10Gbps Directly-Modulated Monolithically-Integrated Novel Dual-Mode Laser as Beating Light Source
Autor: Younghoon Kim, Dong Woo Park, Jinchul Cho, Eui Su Lee, Da-Hye Choi, Jun-Hwan Shin, Mugeon Kim, Seung-Hyun Cho, Sang-Rok Moon, Eon-Sang Kim, Yongsoon Baek, Donghoon Lee, Sang-Ho Park, Young Ahn Leem, Il-Min Lee, Kyung Hyun Park
Publikováno v: Optical Fiber Communication Conference (OFC) 2022.
We demonstrate a photonics-based 300GHz band wireless terahertz (THz) link using our directly modulated novel dual-mode laser (DML) as the beating light source. We have obtained 10Gbps transmission over a single channel.
