Abstract

The tunable liquid crystal random lasers is produced by filled liquid crystal which doped laser dye and scattering particles to the slab photonic crystal defect based on liquid crystal refractive index sensitive to changes in temperature and electric field properties, narrow-band filter characteristics of photonic crystal micro-cavity. The structure of liquid crystal tunable random lasers designed. By use of Maxwell equations and rate equations, the relationship of liquid crystal refractive index with temperature and electric field, the finite difference time domain method and the Matlab programming numerical analysis, the affect of temperature and electric field on wavelength, peak transmission, bandwidth of the liquid crystal random laser.
