Abstract

An optically pumped vertical-cavity surface-emitting laser (VCSEL) was conceived, fabricated, and characterized for stable circularly polarized (CP) emission. This laser includes a columnar thin film as a quarter-wave plate and a chiral sculptured thin film as a chiral mirror for its microcavity. Pure CP lasing with a high degree of CP (∼0:97) was observed when the VCSEL was optically pumped. The polarization of the laser output exhibits the same handedness as that of the chiral mirror.
