Low V? high-speed GaAs travelling-wave electrooptic phase modulators using an n-i-p-n structure (2009)

Abstract In this paper, we report a new design for GaAs modulators based on an n-i-p-n structure. The travelling-wave coplanar waveguide (CPW) electrodes are employed to realize high speed operation. By optimization, an electrical 3-dB bandwidth of nearly 40 GHz (optical 3-dB bandwidth of 80GHz) and a Vpi around 6.6 V are predicted for a 5 mm long phase modulator.
