In this paper we present the design and simulation of 128-channel 10 GHz AWG. The design was performed applying our new developed stand-alone software tool, called AWG-Parameters, and simulated by commercial software tool Optiwave. Simulated transmission characteristics were evaluated using. Wavelength division multiplexing is a method of modulating multiple signals at different wavelengths (channels) to transmit them on a single waveguide or fiber. To begin with, we assume that we have the element parameters from a known process design kit (PDK). The goal is to be able to design an. In this tutorial, we provide an example of how to implement arrayed waveguide gratings (AWGs) for wavelength division multiplexing on the Luceda PDK for AMF.
