Fig. 5.6 The fluctuation analog models of OEO DM (a) and of OEO MZ (b) as QWLD enclosed by
the positive feedback loop “Feedback Chain”. The laser model is presented in the dipole approximation with the controlling population circuit. “Feedback Chain” consists of the optical fiber OF,
the photodetector PD, the RF filter F, the amplifier A. Laser is QWLD, P is the polarizer, C the RF
coupler. PD2 is the photodetector intended for determination of the power values in the MZ
modulator input and/or in the output of the optical fiber
