DOI: 10.1038/s41598-019-49604-0

Abstract: We reported on GaN microcavity (MC) lasers combined with one rigid TiO2 high-contrast grating (HCG) structure as the output mirror. The HCG structure was directly fabricated on the GaN structure without an airgap. The entire… read more here.

Published in 2019 at "IEEE Journal of Selected Topics in Quantum Electronics"

DOI: 10.1109/jstqe.2019.2949457

Abstract: This paper proposes a new design for a nitride-based vertical-external-cavity surface-emitting laser (VECSEL) emitting at 394 nm. The structure contains a monolithic high contrast grating (MHCG) instead of a conventional distributed Bragg reflector (DBR), makes the… read more here.

Published in 2020 at "Optics express"

DOI: 10.1364/oe.396693

Abstract: We report the first experimental parametric analysis of subwavelength monolithic high-contrast grating (MHCG) mirrors. To date, subwavelength grating mirrors have been fabricated by suspending a thin grating membrane in the air or placing it on… read more here.
