  • Abstract
    The carrier induced refractive-index change Delta n in integrated InGaAsP 1.30 mu m interferometer structures is evaluated by 1.55 mu m transmission measurements. At carrier concentrations N from 8*1016/cm3 to 3*1018/cm3 a value of Delta n/N=-1*10-20 cm3 is obtained. A good agreement of the experimental results with theoretical predictions on bandfilling, plasma effect and bandgap shrinkage is demonstrated.
