Electroabsorption Modulators
Optical modulators based on the Franz–Keldysh effect.
An electroabsorption Modulator is a Semiconductor device which can be used for controlling the Intensity of a Laser beam via an electric voltage. Its principle of operation is based on the Franz–Keldysh effect, i.e., a change in the Absorption spectrum caused by an applied electric field, which changes the Bandgap Energy but usually does not involve the excitation of carriers by the electric field.
