摘要: The optical gain properties of InGaN-based green (512 nm) laser diodes fabricated on (0001) GaN substrates are investigated. Fitting simulations to the experimental spectra provides a Gaussian inhomogeneous broadening 95 meV, an confinement factor 0.006, and internal loss as low ~10/cm. remarkable suppression compensate for confinement, leading threshold current density 2.75 kA/cm2. suppressed inhomogeneity contributes highly linear increase with injection carrier, while results in relatively differential mode gain.
