High Temperature Operation of Co-Doped InAs Quantum Dot Laser for O-Band Emission
We demonstrate high temperature operation of InAs quantum dot lasers through active region engineering. We grew an n-doped region within the InAs quantum dot (QD) layer and incorporated a 10 nm p-GaAs modulation-doped layer within a 43 nm GaAs spacer ...

Opportunities of Semiconducting Oxide Nanostructures as Advanced Luminescent Materials in Photonics
The review discusses the challenges of wide and ultrawide bandgap semiconducting oxides as a suitable material platform for photonics. They offer great versatility in terms of tuning microstructure, native defects, doping, anisotropy, and micro‐ and nano‐structuring. The review focuses on their light emission, light‐confinement in optical cavities, and
