Controlled Fabrication and Photonic Structure of Cholesteric Liquid Crystalline Shells

Omnidirectional laser action in W/O/W emulsion with CLC shells is demonstrated. The emulsion, in which the helical axis of the CLC phase is normal to the surface, is successfully fabricated by using a microfluidic device. The whole emulsion system with dispersed core–shell droplets with a CLC shell...

Summary:Omnidirectional laser action in W/O/W emulsion with CLC shells is demonstrated. The emulsion, in which the helical axis of the CLC phase is normal to the surface, is successfully fabricated by using a microfluidic device. The whole emulsion system with dispersed core–shell droplets with a CLC shell can serve as a flexible omnidirectional resonator for dye lasers.
