Fig. 6From: Integrated heterodyne laser Doppler vibrometer based on stress-optic frequency shift in silicon nitrideSimulated side band suppression ratio (SBSR) at the output of the SSB-OFS after coherent detection. The effect of the deviation of a the phase modulation, b the power splitting ratio and c the phase difference between optical paths of the optical circuit from their ideal values is demonstrated in pairsBack to article page
