Our ability to detect, image, and quantify nanoscopic objects and molecules with visible light
has undergone dramatic improvements over the past few decades. While fluorescence has …

Fluorescence is widely used in optical devices, microscopy imaging, biology, medical
research and diagnosis. Improving fluorescence sensitivity, all the way to the limit of single …

Evanescent light excitation is widely used in super-resolution fluorescence microscopy to
confine light and reduce background noise. Here, we propose a method of exploiting …

We propose an all-optical technique for plasmonic structured illumination microscopy (PSIM)
with perfect optical vortex (POV). POV can improve the efficiency of the excitation of surface …

This paper describes the image formation process in optical leakage radiation microscopy of
surface plasmon-polaritons with diffraction limited spatial resolution. The comparison of …

We report the angular distribution of the G and 2D Raman scattering from graphene on glass
by detecting back focal plane patterns. The G Raman emission can be described by a …

Here, we present a 3D localization-based super-resolution technique providing a slowly
varying localization precision over a 1 μm range with precisions down to 15 nm. The axial …

Fluorescence imaging technology has been extensively applied in chemical and biological
research profiting from its high sensitivity and specificity. Much attention has been devoted to …

A technique for high-resolution wide-field fluorescence microscopy by using standing
surface plasmon waves induced by optical vortices (OVs) is proposed, aiming at harnessing …

Strongly confined electromagnetic (EM) fields generated by tightly focused light beams are
applied widely in nano‐optics due to their vectorial characteristics. The inclusion of the …
