Scientists Create Chip That Generates Brand-New Colors of Light, Cracking a Decades-Old Nonlinear Optics Challenge

By harnessing two natural timescales in resonator arrays, researchers created photonic chips that reliably produce multiple harmonics without active compensation. For decades, scientists and engineers have steadily advanced technologies that control and manipulate light. These tools now underpin everything from ultra-precise atomic clocks to the massive data flows moving through modern data centers. As industries [...]
