Phys.org  October 15, 2021 An international team of researchers (Canada, France, China, Australia) developed and demonstrated a self-adjusting on-chip optical pulse-shaper based on the concept of temporal coherence synthesis. The scheme enables on-the-fly reconfigurability of output optical waveforms by using an all-optical sampling technique in combination with an evolutionary optimization algorithm. They showed that particle-swarm optimization can outperform more commonly used algorithms in terms of convergence time. The system combines all key ingredients for realizing fully on-chip smart optical waveform generators for next-generation applications in telecommunications, laser engineering, and nonlinear optics. The team’s next steps include the investigation of more […]
