Abstract: We present high-performance 2.05 $\mu \mathrm{m}$ laser diodes operating at room temperature based on an antimony-free InP-based quantum well structure. Superluminescent diodes with a record ...

Abstract: In this paper, we proposed two kinds of graded AlInGaN last quantum barrier (LQB) structures to improve the optical performance of deep ultraviolet laser diodes (DUV LDs). Through the ...
