(1) Use the Existing Modules / Components for Your Research Papers, Research Projects, Theses and Lab Simulation Experiments.
(2) Modify the Modules / Components to the Next Level for Your Research Papers, Research Projects and Theses.
(3) Integrate Different Modules / Components in the OCSim Package to Realize Your Own Fiber Optic Communication Systems.
(4) Modify the Modules for Co-Simulations with the Third Party Commercial Optical Communication Systems Softwares.


Main Module


Simulation of EDFA gain by solving the coupled differential equations, governing evolutions of signal and pump in erbium doped fiber. This source code calls the matlab built-in program ode45 to solve the nonlinear differential equations. ode45 requires a function edfa_ode.m in which the differential equations are described.

6a.1 Plot gain vs length, signal power vs length and pump power vs length.

6a.2 Modify the source code to plot the gain vs length for various pump input powers ranging from 3 dBm to 12 dBm.

6a.3 Modify the source code to plot the gain vs input signal power ranging from -60 dBm to 0 dBm for various input pump powers. Keep the amplifier length fixed (~ 20 m). Do you observegain saturation at larger input signal powers? Explain. Does the gain saturation depend on the input pump power?
