Abstract :
Summary form only given. In the quest to improve distributed feedback lasers for telecommunication systems, it is critical to be able to characterize these lasers effectively. In this paper, we use out model for the amplified spontaneous emission from DFB lasers coupled with our model for the material gain of strained quantum well lasers to analyze data measured on a 1.55-/spl mu/m InGaAsP-InGaAsP strained quantum well DFB laser in an effort to systematically extract important laser parameters.
