Fig. 6.23 The structure of OEO MZ taking into account the laser, PD, and NA noise source. (a)
The structure of OEO MZ with sources of RF noise: the detected QWLD noise (1), the own noise of
PD (2), noises in the input and output of RF amplifier (3, 4). (b) The structure of OEO MZ as the RF
amplifier with nonlinear characteristics S A , which is covered by the block of the positive feedback
with the conductance Y a . The source of the RF noise are shown: four noise sources presented in (b)
are reduced to the one equivalent noise source ξ n
