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.
Claims15
An electro-optic modulator comprising:
- an AC coupled ground electrode;
- a signal path electrode for carrying an electrical signal, the signal path electrode being disposed substantially parallel to the AC coupled ground electrode;
- and
- a waveguide disposed between the signal path and AC coupled ground electrodes for transmitting an optical signal, for modulating the polarization of the optical signal in accordance with an electric field generated between the signal path and AC coupled ground electrodes in response to the transmission of the electrical signal through the signal path electrode.
