Paper Abstract

We investigated rolls of crystal-field split-off valence band (CH VB) in the deep-UV laser by measuring a transverse-magnetic-field (TM)-mode polarization of lasing and spontaneous surface and edge emissions above and below the lasing threshold from the AlGaN multiple-quantum-well (MQW) laser at 240.8 nm and the anisotropic optical properties of c-plane AlxGa1-xN multiple quantum wells and m-plane AlxGa1-xN single layer. These results indicate that CH VB plays an important role in (E//c) polarization and anisotropic emissions from AlxGa1-xN with x≧0.5.
