Wavelength-variable laser in a hybrid photonic crystal containing ferroelectric liquid crystal
We, have investigated laser action in a hybrid photonic crystal (HPC) composed of ferroelectric liquid crystal (FLC) and dielectric multilayers. Single-mode laser action was observed in the HPC, which was based on a defect made at the bond edge of the FLC. The lasing threshold of the HPC became a thousandth lower than that of the simple FLC without the multilayers. The theoretical calculations of optical characteristics of the HPC and the simple FLC were performed, which was in good agreement with the experimental result. We have demonstrated tuning of the lasing wavelength by applying an electric field.
