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