Abstract
The slow-light effect in silicon lattice-shifted photonic crystal waveguide (LSPCW) Mach–Zehnder modulators allows compact phase shifters, while limiting the working spectrum . We optimized the structural parameters of the LSPCW and extended to cover the full C-band in exchange for moderately decreasing the group index . We obtained with in a fabricated device and observed 25 Gbps eye opening in the 200 μm modulator in the full C-band.
