Paper Abstract

We report the design of a 10 GHz non-return-to-zero (NRZ) silicon modulator based upon 0.25-μm CMOS/BiCMOS processes. The basic optical component is a ridge waveguide slightly-doped with P and N impurities, which forms a reverse-biased P/N junction. The diode typically operates between reverse and zero biases, so as to change the number of free carriers overlapping with the optical mode and consequently modulate the phase of the light. This type of phase shifters form the arms of a push-pull Mach-Zehnder interferometer to realize amplitude modulation.
