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.
In this paper we propose a novel non-iterative optical pulse characterization technique using sinusoidal optical phase modulation, which can work with modulation amplitude up to 1.9 radians. The larger usable modulation amplitude would make the proposed method more tolerable to noise present in the recorded pulse spectrum after undergoing phase modulation. The method is then validated experimentally...
GaAs-based electrooptic phase modulators using an n-i-p-n structure and coplanar waveguide traveling-wave electrodes are designed using the compact 2-D finite-difference time-domain technique and Pade approximation transform. By optimization, an electrical 3-dB bandwidth of 40 GHz and a 6.6-V Vpi are predicted for a 5-mm-long modulator.
