Generation of S-shaped photonic hooks from microcylinders with engineered surface patches
Chu Xu, Fen Tang, Qingqing Shang +8
Photonic hooks (PHs) are non-evanescent light beams with a highly concentrated curved optical fields. Since their discovery, PHs always have one single inflection point and thus ha…
Generation of photonic hooks from patchy microcylinders
Fen Tang, Qingqing Shang, Songlin Yang +4
The photonic hook (PH) is new type of curved light beam which has promising applications in various fields such as nanoparticle manipulation, super-resolution imaging, etc. Herein,…
Super-resolution imaging with patchy microspheres
Qingqing Shang, Fen Tang, Lingya Yu +6
The diffraction limit is a fundamental barrier in optical microscopy, which restricts the smallest resolvable feature size of a microscopic system. Microsphere-based microscopy has…
Refractive index sensing with hybrid surfaces of photonic crystals and dielectric microsphere monolayers
Cheng Fang, Qingqing Shang, Fen Tang +2
In this work, a refractive index (RI) sensor with an effective integration of colorimetric detection and optical sensing capabilities has been developed. Colorimetric detection rel…
