Monodisperse and size-modulable spherical optical resonators produced from synthetic polymers by inkjet printing toward applications under water†

Abstract

Micro-spherical optical resonators with high monodispersity and size-modulability are produced from synthetic polymers using an inkjet printing method. The high surface smoothness and sphericity of the synthetic polymer particles contribute to the efficient light confinement inside the particles via whispering gallery mode (WGM) optical resonance in water, demonstrating their suitability for chemical and biological applications.
