Performance Enhancement of Passive Optical Communication Link with Co-simulation Approach

This work investigates the performance enhancement achieved for an optical communication link designed using co-simulation platform provided by Optisystem and OptiSPICE. A passive optical network with a single channel is designed that employs external Mach–Zehnder modulator at the transmitter and direct detection at the receiver end. The design is first simulated at 2.5 Gbps with Optisystem v.13 only. Externally modulated laser circuit is then designed in OptiSPICE v.5 and this circuit’s co-simulation is done with a design made in Optisystem. The simulation results validate the superior performance obtained when optical components are designed using OptiSPICE that provides more control over user adjustable parameters for different components. The same design parameters can be emulated for practical implementation of Passive optical Network system.
