Abstract

The invention discloses a method for detecting resonant wavelength shift of an integrated resonant ring. A pair of lasers with a frequency difference are generated to serve as detecting optical signals after a single-frequency laser passes through the integrated resonant ring; the resonant wavelength shift amount is obtained through detection of the phase difference of the detecting optical signals. According to the method, a phase detection method is adopted, the intensity noise caused by the factors of the stability of a light source, vibration of an optically coupled system between the integrated resonant ring and an integrated chip is effectively reduced, and the detecting accuracy is improved.
