Abstract

Vector beam lasers are highly desirable for wide applications ranging from manipulation to communications. In this paper, we report the first directly modulated vector beam laser with azimuthally polarized emission. It’s a microcylinder cavity added with proper second order grating on the top, which enables single-mode lasing and efficient surface emission. Through theoretically and numerically analysis, the lasers are designed in detail. With optimized top grating, the emission is azimuthally polarized vector beam.
