3C10 ネマティック液晶を導波路コア層とした干渉光励起レーザー発振の電界制御(フォトニクス・光デバイス)

Optically pumped distributed feedback (DFB) lasing has been demonstrated in a dye-doped nematic liquid crystal (NLC) waveguide by holographic excitation. The excitation was performed by two-beam interference using Lloyd mirror configuration. With an applied electric field, continuous tuning of the lasing wavelength was realized due to the change of the effective refractive index of the NLC core layer caused by the reorientation of NLC molecules.
