We demonstrate a 1D micro-cavity film based on cholesteric liquid crystals and reactive mesogens. The 1D micro-cavity film was applied in reflective display and liquid crystal laser. In terms of display, the reflective light from 1D micro-cavity film can be switched between scattering state and reflective state, through a driven layer with dual-frequency cholesteric liquid crystal. In terms of liquid crystal laser, a distributed feedback laser was realized, with peak wavelength of 621 nm and narrow linewidth of 0.4 nm. The threshold of the laser was 20 mu J/pulse. The 1D micro-cavity film can be used in reflective display, liquid crystal laser, liquid crystal blackboard and others optical and photonic devices. (C) 2016 Optical Society of America
