Compared to conventional, identical width quantum well (IWQW) material, we have broadened the gain spectrum by around 35% using multiple width quantum well (MWQW) material. For colliding pulse mode-locked laser, pulse width shortening of around 9.2% is obtained for the MWQW device in comparison to the IWQW device.
