Paper Abstract

In this work we show the analysis of high contrast vertical-cavity surface-emitting lasers (VCSEL) mirror with etched photonic crystal, which provide the true photonic band-gap (PBG) for TE-like polarized light. We confirm that PBG is the main light confinement mechanism by analyzing a low-index line-defect as well as a low-index cavity mode. In the latter case we are able to obtain very high cavity Q-factor. Such PBG-VCSELs are compatible with the VCSEL technology and do not require a complicated assembly of three-dimensional photonic crystals.­
