Nano rainbows advance the light spectrum at the nanoscale

Sydney, Australia (SPX) Jan 14, 2025

Since lasers emerged in 1960, nonlinear optics has sought to expand light's spectral range and generate new frequency components. Among the many techniques, supercontinuum (SC) generation is notable for producing light that spans wide sections of the visible and infrared spectrum. Traditionally, SC sources rely on third-order optical nonlinearity, requiring long interaction lengths to achieve br
