IntroductionSingle Channel2-Channel WDM4-Channel WDM8-Channel WDMSummary of ResultsThis example goes through the design of an 8-channel WDM. Our goal is to design an 8-channel WDM system with a comb laser as the input, cascaded ring modulators to modulate and multiplex the signals, and cascaded ring resonators to demultiplex. In the wdm_8channels_1.icp simulation file, we start with all of these components and check the eye diagr...See more on optics.ansys Wikipedia
A WDM system uses a multiplexer at the transmitter to join the several signals together and a demultiplexer at the receiver to split them apart. With the right type of fiber, it is possible to have a device that does both simultaneously and can function as an optical add-drop multiplexer. The optical filtering devices used have conventionally been etalons (stable solid-state single-frequency Fabry–Pérot interferometers in the form of
Analytical calculations of the proposed Wavelength Division Multiplexing (WDM) system are also verified up to 500 km length of optical fiber transmission.
At the transmitting end there are several independently modulated light sources, each emitting signals at a unique wavelength. Here a wavelength multiplexer is needed to combine these optical outputs into
