| Abstract(in English) | Mechanisms of the electron depleting absorption control(EDAC)in semiconductor optical modulator are theoretically and experimentally examined.In an impurity doped direct-transition- type semiconductor material,optical absorption is enhanced by depleting the carriers,through three physical phenomena induced in the depleting region:1)a decrease in the number of electrons(or holes)located in the conduction(or valence)band resulting in increase of the band-to-band and band-to-impurity atom transition probabilities,2)a decrease in the screening effect on the ionizedimpurity atoms resulting in shift of the impurity energy levels,and 3)an increase in the electric field in the depletion layer inducing Franz-Kledysh effect.These three phenomena work to enhance the optical absorption. |
