Paper Abstract

In this paper, we present a calculation of the linewidth enhancement factor for the electro absorption modulator. A model of the quantum confined stark effect (QCSE) is described. The absorption coefficient at different field is calculated. Through the well known Kramers-Kronig relationship, the induced refractive index change has been determined. The calculated linewidth enhancement factor ((alpha) -factor) varies with the applied electric field. This variation is in the 0.1 to 0.3 range.
