Abstract
We report experimental demonstration and modeling of all-optical on-chip
non-return-to-zero (NRZ) to pseudo-return-to-zero (PRZ) format conversion
using narrow-band silicon microring resonator-based notch filters. Our proof-of-principle
experiment using a carrier-injection-based tunable silicon microring resonator
demonstrates NRZ-to-PRZ conversion at 3.6 Gbit/s.
Our Fourier-transform-based modeling reveals in detail the format conversion
dependence on the microring resonance Q factor, extinction ratio, phase response,
and NRZ signal transition times, assuming signal format conversion of 40 Gbit/s.
