The photonic crystal liquid crystal fiber grating (PCLCFG) is produced by filled the helix liquid crystal in the photonic crystal fiber core air column. The transmission characteristics of the PCLCFG is study by space filling mode and the mode coupling theory as well as the transmission matrix, and has carried on the theoretical calculation and the simulation with Matlab. The results show that to...
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...
