Abstract

A versatile "capillary-bridge lithography" technique is developed for patterning 1D organic single crystals and microring structures through controlling the generation and dewetting of capillary bridges on an interface with asymmetric wettability. High-performance Fabry-Pérot and whispering-gallery mode lasing emission with tunable modes are achieved on these 1D and microring structures.
