High quality-factor (Q factor) optical micro-resonators can tightly confine light, allowing the generation of nonlinear optical effects efficiently within the resonator, even if a continuous optical input is used. The photo shows an optical micro-resonator made of silica when a single-wavelength infrared light is input and is observed from the top and side. An optical comb is generated when four-wave mixing occurs. Then, visible light is obtained via optical third harmonic generation. By changing the conditions such as the power of the optical input and wavelength, the color changes to green and red. (p.181)
