Abstract(in English) | In this study, we investigated polarization characteristics of GaN-based VCSELs. In particular, dependences of substrate off-direction and electrode arrangement direction on the polarization direction were investigated. We fabricated two types of VCSELs grown on GaN substrates with 0.4o off-angle towards m-axis direction. One was a perpendicular case and the other was a parallel case in a relation between the substrate off-direction and the electrode arrangement direction. We measured polarization directions of more than 20 VCSELs in each case. As a result, 45% VCSELs in the perpendicular case and 67% VCSELs in the parallel case showed that the polarization direction corresponded to the substrate off-direction. In other words, total more than 60% VCSEL showed such a polarization direction, suggesting that the substrate off-direction even with the slight off-angle determined the polarization direction to some extent. |
