Coherent Plasmonic Absorption in the Femtosecond Regime
Venkatram Nalla, Xu Fang, João Valente +2
Dissipation of electromagnetic energy through absorption is a fundamental process that underpins phenomena ranging from photovoltaics to photography, analytical spectroscopy, photo…
Controlling light with light using coherent meta-devices: all-optical transistor, summator and invertor
Xu Fang, Kevin F. MacDonald, Nikolay I. Zheludev
Although vast amounts of information are conveyed by photons in optical fibers, the majority of data processing is performed electronically, creating the infamous 'information bott…
Ultrafast all-optical switching via coherent modulation of metamaterial absorption
Xu Fang, Ming Lun Tseng, Jun-Yu Ou +3
We report on the demonstration of a femtosecond all-optical modulator providing, without nonlinearity and therefore at arbitrarily low intensity, ultrafast light-by-light control.…
Coherent excitation-selective spectroscopy in planar metamaterials
Xu Fang, Ming Lun Tseng, Din Ping Tsai +1
In a proof-of-principle experiment with metamaterials exhibiting electric dipolar and magnetic dipolar resonances, we demonstrated that the electric and magnetic resonances can be…
Influence of Intrinsic Electronic Properties on Light Transmission through Subwavelength Holes on Gold and MgB2 Thin Films
Xu Fang, Chenggang Zhuang, Zhenchao Wen +7
We show how intrinsic material properties modify light transmission through subwavelength hole arrays on thin metallic films in the THz regime. We compare the temperature-dependent…
Composite metamaterials with dual-band magnetic resonances in the terahertz frequency regime
Ming Li, Zhenchao Wen, Jinxin Fu +5
Composite metamaterials(CMMs) combining a subwavelength metallic hole array (i.e. one-layer fishnet structure) and an array of split-ring resonators(SRRs) on the same board are fab…
