| Abstract(in English) | Intersubband transition (ISBT) in GaN/AlN super lattice system is very attractive phenomenon due to ultrafast absorption relaxation (～100fsec) and possibility of application in optical communication wavelength region. In this study, GaN/AlN superlattices were grown by RF-plasma assisted molecular beam epitaxy on (0001) sapphire substrate. By use of SiO_2 rib-waveguide structure, light polarization dependency of ISBT was observed. The ISBT absorption coefficient was systematically evaluated for wide carrier concentration range from 1x10^<18> to 3x10^<20>cm^<-3>. The free carrier absorption coefficient was also estimated by waveguide measurement. |
