Gain Compression and Linewidth Enhancement Factor in Mid-IR Quantum Cascade Lasers

Abstract

We have observed and quantified the adiabatic and transient chirp in a directly modulated quantum cascade laser (QCL). Those wavelength tuning effects are well-characterized in diode lasers, and the rate equation model that successfully describe the diode laser behavior also provides an excellent fit for the QCL data. In this study, we have extracted the… (More)
