Abstract
A semiconductor based electro-optic modulator comprising a capacitively coupled ground allowing for DC biasing of the modulator and a pre-distortion circuit for alleviating RF skin effect and for increasing bandwidth of modulator. Electrical components and functions of modulator partly located on an alumina pane. Reduction of thermally-induced stresses by connecting modulator ground to package ground via alumina pane is also disclosed.
