Abstract

In this paper, the static and dynamic performance of multi quantum-well (MQW) 1.3 micrometer InGaAsP Fabry Perot lasers is assessed experimentally and theoretically to identify the mechanisms responsible for impaired high speed performance at elevated temperature. Initially, threshold currents and spontaneous emission spectra are characterized for a range of temperatures from room temperature to 85 degrees Celsius to indicate a significant increase in non-radiative current contributions. Preliminary estimates are made for the contributions of leakage and Auger recombination rates, found from the dependence of integrated spontaneous emission with carrier density. Drift-diffusion modeling is found to accurately predict the trend of threshold currents over temperature. Using gain modeling good agreement is found between the measured and predicted integrated spontaneous emission intensity. Gain measurements at 85 degrees Celsius indicate a reduction in RIN frequency to 63% of the 25 degree Celsius value which matches well with experimental small signal performance.
