Double-heterostructure GaAs : Si diode lasers

Abstract
Double‐heterostructure diode lasers with Si‐doped active regions have exhibited laser action within the wavelength range 9100–9500 Å under pulsed room‐temperature conditions. Threshold current densities are typically 4 × 103−1.1 × 104 A/cm2, and total power conversion efficiencies are ∼ 1–3%.
