IQ modulator bias controller
The MBC-IQ-LAB is an electronic system able to control I&Q Modulators in a CS-SSB modulation scheme. It is based on the minimization of the beating harmonic of two small dithers. This system allows to maintain harmonic rejection of optical CS-SSB spectrum better than 40dB over tens of hours.
