Gain-assisted critical coupling for enhanced optical absorption in graphene
Tingting Liu, Chaobiao Zhou, Shuyuan Xiao
Enhanced optical absorption in two-dimensional (2D) materials has recently moved into the focus of nanophotonics research. In this work, we present a gain-assisted method to achiev…
Axial cosinoidal structured illumination using phase modulation
Xianlin Song, Jianshuang Wei, Lingfang Song
We propose a novel method for generating axial cosine structured light by using phase-only spatial light modulator. We implemented axial cosine structured light using holographic t…
Parallel multifocus optical-resolution photoacoustic microscopy based on tunable acoustic gradient lens and fiber delay network
Xianlin Song
We developed a multifocus optical-resolution photoacoustic microscope (MPAM) with extended depth of field (DoF) by using a tunable acoustic gradient (TAG) lens and a pulse delay me…
Controlling light absorption of graphene at critical coupling through magnetic dipole quasi-bound states in the continuum resonance
Xing Wang, Junyi Duan, Wenya Chen +3
Enhancing the light-matter interaction in two-dimensional (2D) materials with high- resonances in photonic structures has boosted the development of optical and photonic devices…
Engineering light absorption at critical coupling via bound states in the continuum
Shuyuan Xiao, Xing Wang, Junyi Duan +4
Recent progress in nanophotonics is driven by the desire to engineer light-matter interaction in two-dimensional (2D) materials using high-quality resonances in plasmonic and diele…
Imaging through Fano-resonant dielectric metasurface governed by quasi-BIC
Chaobiao Zhou, Shiyu li
Fano resonance has raised great attention in nanophotonics attributing to its unique properties.In this work, we study the imaging function of Fano-resonant silicon metasurfece gov…
