Abstract.  A self-calibrated electrical method to measure magnitude response of optical filters is proposed based on dual-frequency-shifted heterodyne. The combined response of optical modulation, filtering, and photodetection is determined from the first frequency-shifted heterodyne, while the reference response of optical modulation and detection is simultaneously obtained from the second frequency-shifted heterodyne, with which the magnitude response of optical filter under test is extracted and self-calibrated. Our method eliminates the extra separate calibration to correct the responsivity fluctuation in the optical modulation and detection. Moreover, it extends double frequency range due to both upper and lower frequency direction measurement at every swept frequency. Magnitude response of optical filter is experimentally measured with our method and compared to that with the conventional method to check its consistency.
