Abstract
The theoretical model and mathematical description of dual-balanced coherent detection ( or dual-balanced coherent detection ) are established,with which the current formula and output power formula of intermediate frequency (IF) signals are deduced. Theoretical analysis shows that this dual-balanced coherent detection technique can effectively solve the polarization matching of signal light and local light, and improve the stability of signal measurement, and reduce the influence on signal-to-noise ratio (SNR) of the system. Meanwhile, the technique also have the above advantages compared with single-balanced coherent detection. Hopefully, the dual-balanced coherent detection method could be applied in a wide range of fields.
