III-Nitride vertical-cavity surface-emitting lasers (VCSELs) have attracted much attention
during the last two decades. Control of the laser polarization in VCSELs is one of the main …

Ultraviolet light is essential for disinfection, fluorescence excitation, curing, and medical
treatment. An ultraviolet light source with the small footprint and excellent optical …

Since the first demonstration of (Al, In, Ga) N-based blue vertical-cavity surface-emitting
lasers (VCSELs) in 2008, the maximum output power (Pmax) and threshold current density …

This Letter reports a new method for the generation of optical vortices using a
micropatterned optical fiber tip. Here, a spiral phase plate (2 π phase shift) is micromachined …

Optically pumped wavelength-tunable vertical-cavity surface-emitting lasers (VCSELs)
operating in the ultraviolet A (UVA) spectrum were demonstrated. The VCSELs feature …

We report GaN-based vertical-cavity surface-emitting lasers (VCSELs) with buried GaInN
tunnel junctions (TJs). Under room-temperature continuous-wave operation, the VCSEL with …

In this paper, we reported on wafer-scale nanoporous (NP) AlGaN-based deep ultraviolet
(DUV) distributed Bragg reflectors (DBRs) with 95% reflectivity at 280 nm, using epitaxial …

GaN-based vertical-cavity surface emitting lasers (VCSELs) have attracted significant
attention in recent years for their potential applications in solid-state lighting, optical …

Due to their unique properties, III-nitride vertical-cavity surface-emitting lasers (VCSELs) are
expected to enable several applications ranging across communication, sensing and …

III-nitride materials are used for ultraviolet (UV) and visible light emitters. One such light
source is the vertical-cavity surface-emitting laser (VCSEL) that could find applications within …
