| Abstract | ||
| The capture and escape time constants are a small and finite capture and escape time of the carriers between the separate confinement (SCH) region and the quantum well. These time constants are in picosecond time scale and are important in the direct modulated quantum well lasers which these small time constants are effected on the gain compression factor where the gain compression factor is effected on the differential gain . The differential gain is one from the important factors for the enhanced performance for the direct modulated quantum well lasers which the output this lasers are depended on it | ||
