Abstract
Section titled āAbstractāA design that couples the transparent silica microsphere to the AFM probe and deposits the diamond tip at the bottom of the microsphere is studied when illuminated with a plane wave. A controllable curved photonic nanojet (PNJ) named photonic hook (PH) can be generated on the backlight side, which can be explained as an interference phenomenon caused by the breaking of particle symmetry. The influence of the size, position of the tip and the diameter of microlens on the PH focusing on the outside of the microlens is studied. The simulation results show that these parameters can be used to control the bending characteristics of PH.
