ABSTRACT:
Multimode switching is obtained in a four-port device having controllable switching means (22) comprising a thin Fabry-Perot interferometer including, within the cavity, a voltage controllable absorber (35). By the appropriate dimensioning of the cavity and orientation of the incident radiation, multimode operation is obtained.
