ABSTRACT:
An electro-optical device comprising a CCD structure having charge wells, the charges therein being controlled by a modulating signal applied to said CCD structure. A multiple quantum well structure having quantum well regions associated with the charge wells of said CCD structure, the charges in the CCD charge wells determining the value of the electric fields at said quantum well regions and, hence, the electro-absorption effects at said quantum well regions. The intensity of an input electromagnetic wave signal directed through said electro-optical device is thereby spatially modulated by the electro-absorption effects at the quantum well regions of the multiple quantum well structure. A novel CCD structure using quantum well regions to form the charge wells thereof can be used as the CCD structure for controlling the electric fields at the multiple quantum well structure.
