“…Software emulation is a dynamic simulation analytical method. VPI [11,12,13] and Simulink [14,15,16] are the examples of software emulation method. These software emulation tools construct homodyne OPLL behavioral model to emulate the operation of homodyne OPLL first, then make transient analysis for each node of homodyne OPLL.…”

Homodyne optical phase-locked loop (OPLL) is one kind of PLLs applied in optical field to achieve phase locking between two optical signals. Although there are already some software emulation and s-domain modeling methods studied for homodyne OPLL, few studies about z-domain model of OPLL are reported. For homodyne digital OPLL(DOPLL), the performance of homodyne DOPLL can be analyzed more accurately by z-domain model. So a z-domain modeling methodology for homodyne DOPLL is proposed in the letter. In the proposed methodology, optical related components and analog to digital converter (ADC) are treated as one group. Then with formula transformation, z-domain model for homodyne OPLL is built successfully. Finally, a case study is given, several simulations by z-domain model and Simulink behavioral model are made with the same design parameters. These simulation results agree very well and verify the correctness of z-domain model.
