Separating substances by their chirality faces great challenges as well as opportunities in chemistry and biology. In this study, we propose an all-optical solution for passive sorting of chiral objects using chirality-dependent lateral optical forces induced by judiciously interfered fields. First,...

Abstract Plasmonic materials can generate strong electromagnetic fields to boost the Raman scattering of surrounding molecules, known as surface-enhanced Raman scattering. However, these electromagnetic fields are heterogeneous, with only molecules located at the ‘hotspots’, which account for ≈ 1% o...

Ghost diffraction and ghost imaging are investigated in a lensless imaging system. The evolution process from ghost diffraction to ghost imaging is discussed when the object is moved far away from the source in the test arm. The relation of ghost diffraction and imaging is also studied, and it is fo...
