Abstract :
The spectral measurement of an ultra-high quality-factor (Q) photonic crystal nanocavity using a single-sideband electro-optic modulator made of lithium niobate is described. This technique provides a simple and powerful way to measure the spectral response of ultra-high-Q cavities that have a Q of 1 million. Such cavities are usually difficult to measure with a tunable laser diode or an acousto-optic frequency shifter
