We propose theoretically and demonstrate experimentally white-light whispering gallery mode resonators. These resonators have essentially a continuous modal spectrum accompanied by ultrahigh-Q frequency-independent quality factors. Applications of the resonators for ringdown spectroscopy and light modulation are discussed.
