AN EXPERIMENTAL INVESTIGATION OF GERMANIUM DIODES OF VARIOUS GEOMETRIES AS INFRARED MODULATORS.
Abstract
Two newly designed germanium diodes are investigated to determine their infrared absorption properties as a function of current. Both designs work well but can be improved through better junction formation methods and through the use of lower resistivity material. It is shown that the process of free-carrier absorption is independent of the size or shape of the device, thus allowing considerable freedom in selecting more compact and efficient designs. A new design is proposed which includes the best features of the rectangular and trapezoidal modulators.
