  • Abstract
    A simple analytic method of extracting both the modulus and phase of the CPR from the asymmetric modulated intensity spectrum has been applied to a GaAlAs channelled-substrate-planar (CSP) laser. Knowledge of the phase is extremely useful for modelling laser dynamics. In particular, our results show a marked phase shift which appears consistent with a nonuniform lateral carrier distribution in the CSP laser.
