Abstract
We demonstrate a measurement technique fur determining the contributio n of carrier transport effect on the maximum modulation bandwidth in q uantum well lasers. This technique independently measures the ratio of the effective carrier capture to escape times, as well as the contrib ution from intraband damping mechanisms, in an operating laser. Every single parameter in the present model for modulation dynamics of quant um well lasers can now be determined experimentally, which enables a c onsistency check on its validity.
