Large-Area and Ultrathin MEMS Mirror Using Silicon Micro Rim

Autor: Myeong-Su Ahn, Jaehun Jeon, Kyung-Won Jang, Ki-Hun Jeong

Publikováno v: Micromachines, Vol 12, Iss 7, p 754 (2021)

A large-area and ultrathin MEMS (microelectromechanical system) mirror can provide efficient light-coupling, a large scanning area, and high energy efficiency for actuation. However, the ultrathin mirror is significantly vulnerable to diverse film de

Visible to near-infrared single pixel microspectrometer using electrothermal MEMS grating

Autor: Jaehun Jeon, Jung-Woo Park, Gi Beom Kim, Myeong-Su Ahn, Ki-Hun Jeong

Publikováno v: Optics Express. 31:14583

Compact spectrometers facilitate non-destructive and point-of-care spectral analysis. Here we report a single-pixel microspectrometer (SPM) for visible to near-infrared (VIS-NIR) spectroscopy using MEMS diffraction grating. The SPM consists of slits,

Extraordinary sensitivity enhancement of Ag-Au alloy nanohole arrays for label-free detection of

Autor: Charles Soon Hong, Hwang, Myeong-Su, Ahn, Ki-Hun, Jeong

Publikováno v: Biomedical optics express. 12(5)

Alloy nanostructures unveil extraordinary plasmonic phenomena that supersede the mono-metallic counterparts. Here we report silver-gold (Ag-Au) alloy nanohole arrays (α-NHA) for ultra-sensitive plasmonic label-free detection of

Ag/Au Alloyed Nanoislands for Wafer-Level Plasmonic Color Filter Arrays

Autor: Charles Soon Hong Hwang, Ki-Hun Jeong, Taerin Chung, Youngseop Lee, Myeong-Su Ahn

Publikováno v: Scientific Reports
Scientific Reports, Vol 9, Iss 1, Pp 1-7 (2019)

Alloyed metals in nanoscale exhibit some intriguing features that are absent in mono-metallic nanostructures. Here we report silver and gold alloyed nanoislands with high tunability of localized surface plasmon resonance (LSPR) wavelength in the visi

Nanoislands as plasmonic materials

Autor: Youngseop Lee, Sang-In Bae, Charles Soon Hong Hwang, Taerin Chung, Wonkyoung Lee, Ki-Hun Jeong, Myeong-Su Ahn

Publikováno v: Nanoscale. 11(18)

Subwavelength metal nanoislands thermally dewetted from a thin film emerge as a powerful and cost-effective photonic material, due to the formation of substantially strong nano-gap-based plasmonic hot spots and their simple large-area nanofabrication
