An ultra-broadband photonic-chip-based parametric amplifier
Nature, Published online: 12 March 2025; doi:10.1038/s41586-025-08666-zAn optical parametric amplifier based on integrated photonic circuits fabricated using low-loss gallium phosphide-on-silicon dioxide demonstrates improved bandwidth and gain performance over state-of-the-art erbium-doped fibre amplifiers while maintaining a low noise figure.
