We propose and demonstrate the fundamental operation of a novel on-chip microring resonator-type serial-to-parallel conversion scheme for all-optical label processing. We left out a delay between the simultaneously implemented pump pulses and probe bits to be extracted. This enabled us to utilize free-carrier dispersion effect to concurrently blue shift the resonance spectra of the microring resonators at low pump power, and avoid nonlinear loss due to two-photon absorption. We successfully extracted two consecutive bits of probe packets into separate waveguides and verified the potential of our scheme in the intended application.
