Optical trapping is a powerful tool for manipulating microscopic particles, but conventional approaches often suffer from limited trapping range and poor stability when particles disturb the optical ...

The team demonstrates a gradient-thickness-protected microbottle resonator that enables large-scale, stable optical trapping via whispering-gallery modes. By introducing a controlled wall-thickness ...
