Paper Abstract

We construct an external cavity diode laser (ECDL) comprising structurally left-handed chiral sculptured-thin-film (STF) mirrors for pure circular-polarized (CP) emission, and observed single mode, left-handed CP lasing performance. The extinction ratio of CP output was found to increase rapidly near the threshold of the injection-current for the laser diodes.
