Miniaturizing Color-Sensitive Photodetectors via Hybrid Nanoantennas towards Sub-micron Dimensions
Jinfa Ho, Zhaogang Dong, Hai Sheng Leong +10
Digital camera sensors utilize color filters on photodiodes to achieve color selectivity. As color filters and photosensitive silicon layers are separate elements, these sensors su…
Tunable Mie Resonances in the Visible Spectrum
Li Lu, Zhaogang Dong, Febiana Tijiptoharsono +7
Dielectric optical nanoantennas play an important role in color displays, metasurface holograms, and wavefront shaping applications. They usually exploit Mie resonances as supporte…
High-Efficiency Ultra-Violet Dielectric Meta-Holograms with Antiferromagnetic Resonances
Kun Huang, Jie Deng, Hai Sheng Leong +4
Metasurfaces with spatially varying subwavelength structures enable full control of electromagnetic waves over a wide spectrum. High-efficiency metasurfaces, especially in a transm…
Mode splitting of surface plasmon resonances in super-period metal nanohole gratings
Junpeng Guo, Haisheng Leong
We experimentally observed the surface plasmon resonance mode splitting in a super-period metal nanohole grating under the transverse magnetic polarization excitation. The mode spl…
Investigation of Surface Plasmon Resonance in Super-Period Gold Nanoslit Arrays
Junpeng Guo, Haisheng Leong
Surface plasmon resonance in super-period metal nanoslits can be observed in the first order diffraction as well in the zeroth order transmission. In this paper, surface plasmon re…
