Wafer Scale III-Nitride Deep-Ultraviolet Vertical-Cavity Surface-Emitting Lasers Featuring Nanometer-Class Control of Cavity Length. [PDF]

open access: yesAdv Sci (Weinh)
A DUV‐VCSEL strategy featuring the nanometer‐class control of the cavity length is proposed in the DUV optoelectronic framework based on GaN templates. After the sapphire removal, a self‐terminated etching technology is developed, whereby the cavity length can be accurately determined by epitaxy instead of the fabrication process. As such, a record low

Surface-emitting ring quantum cascade lasers. [PDF]

open access: yesNanophotonics
Abstract This review highlights the development and diverse applications of surface‐emitting ring quantum cascade lasers. These lasers, featuring a ring‐shaped cavity and a second‐order distributed feedback grating, enable controlled surface emission, stable single‐mode operation, and collimated, circularly symmetric beams.
