| Abstract(in English) | We report on the electromagnetic field and far field pattern(FFP) under transverse-multimode operation of blue-violet InGaN semiconductor lasers. Since GaN used as substrate on InGaN lasers is transparence at wavelength of 400nm band, it is difficult to make the transverse high order mode cutoff and electromagnetic field may leak into the substrate direction. These phenomena are theoretically analyzed. In addition, despite the propagation gain for the transverse high order mode is smaller than for the transverse fundamental mode, the high order mode may oscillate as well as the fundamental mode by asymmetric gain. In this result, FFP may be disturbed. This phenomenon is theoretically analyzed, and theoretical and experimental results are compared. |
