Abstract
Modulation format is a key determinant to the performance of an optical communication network. In this work, we study a silicon phase shifter arranged around rib waveguide topologies and explore its potential to be applied in quadraturephase- shift-keying (QPSK) optical modulators. Optical QPSK is implemented with four silicon phase shifters embedded in a nested Mach-Zehnder waveguide. Modulated QPSK signal is simulated by calculating the interference between light beams pass through each phase shifter. The constellation diagram of modulated QPSK signal is calculated after coherent demodulation.
