Periodic Loading and Selective Undercut Etching for High-Impedance Traveling-Wave Electroabsorption Modulators

Periodic Loading and Selective Undercut Etching for High-Impedance Traveling-Wave Electroabsorption Modulators

For the first time, selective undercut etching and periodically loaded electrodes are combined to improve impedance and velocity matching for traveling-wave electroabsorption modulators. These devices are fabricated in a platform compatible with widely tunable lasers.
