Abstract:We report a multi-population rate-equation based numerical model for investigating broadband two-section InAs/InP quantum-dash laser. The model incorporates the quantum-wire-like nature of dashes along with the inhomogeneous broadening of the active region. Numerical results of light power-injection current and spectral characteristics at various absorber section lengths are shown to be in good agreement with the experimental results. Moreover, inhomogeneous broadening displayed a pivotal role in achieving lar… Show more
