Single mode high-contrast subwavelength grating vertical cavity surface emitting lasers
Michael C. Y. Huang, Ye Zhou, and Connie J. Chang-Hasnain
We present a single mode vertical-cavity surface-emitting laser (VCSEL) utilizing a single-layer, high-contrast subwavelength grating (HCG) based top mirror, which provides both the ultrahigh reflectivity and lateral transverse modes control. Experimentally, we demonstrate that merely 11 HCG stripes ... [Appl. Phys. Lett. 92, 171108 (2008)] published Wed Apr 30, 2008.
