Abstract

The state filling effect has been suggested as a source responsible for the degradation of modulation bandwidth in quantum well lasers compared to the expected value reviously calculated [1]. According to this theory, an increase in energy difference between the confined quantized energy state in the well and the energy states in the graded index separate confinement heterostructure (GRINSCH) region will restore the differential gain to a certain extent. A proper tailoring of the GRINSCH region will therefore (increase) improve the speed behavior of the quantum well lasers.
