Efficient and Broadband Four-Wave Mixing in AlGaAs Microresonator for High-Speed Optical Signal Processing

We demonstrate four-wave mixing in GHz-linewidth AlGaAs microresonators with −10.7-dB conversion efficiency at 4-mW pump power over the telecom S-, C- and L-bands. We achieve 57-dB resonance enhancement for microresonators supporting 10-Gbit/s signal processing.
