"small, energy efficient, accurate frequency comb creating frequency range (light colors)... thin film lithium niobate enables broad range of light to pass, different colors to interact with each other generating new colors, and produces continuous output rather than light pulses, reducing input power by order magnitude... comb lines farther from center spectrum not less intense, offering greater measurement accuracy... sensing, spectroscopy, medical diagnostics, fiber-optic communications, wearable health-monitoring devices"
