Mach-Zehnder Interferometer Switch

This lesson outlines the design process of an electro-optic 2×2 switch based on integrated Mach-Zehnder interferometer. An electro-optic switch is a device used in integrated fibre optics. The device is based on Mach-Zehnder interferometer made by Titanium diffusion in Lithium Niobate substrate. The switching between the ports is achieved by an electro-optic effect within such…

Lesson 1: Transmitter — External Modulated Laser

This lesson describes how to create a transmitter using an external modulated laser. You will become familiar with the Component Library, the Main layout, component parameters, and visualizers. To start OptiSystem, perform the following procedure: Starting OptiSystem Figure 1: OptiSystem graphical user interface Main parts of the GUI The OptiSystem GUI contains the following main…

Lesson 2: Subsystems — Hierarchical Simulation

A subsystem is like a component — it has an icon, parameters, and input and output ports. You build a subsystem using a group of components or other subsystems. You can easily create a subsystem by grouping selected components in the layout (see Figure 1). Subsystems help you to create your own components based on…

Lesson 3: Optical Systems — WDM Design

This lesson describes how to simulate a WDM system with 8 channels. You will become familiar with the Component Library, parameter groups, and visualizers such as the BER Analyzer. Global parameters For this simulation we will use default parameters for the Bit rate, Bit sequence length, and Sample rate. Viewing the global parameters To view…

Lesson 4: Parameter Sweeps — BER x Input Power

This lesson describes how to combine the results from the BER/Eye Analyzer with the signal input power using parameter sweeps. You will become familiar with parameter sweeps, graph builder, results, graphs, and views. The first three procedures describe how to iterate the Power parameter for the CW Laser component. Opening the sample file Use the…

Lesson 5: Bidirectional Simulation — Working with Multiple Iterations

Besides the typical global simulation parameters of OptiSystem, such as Bit rate, Samples per bit and Sequence length, there are two additional parameters that are very important when designing bidirectional systems or systems with closed loops, such as ring networks. These parameters are Iterations Initial delay Iterations force a component to calculate again until it…

Lesson 6: Time-Driven Simulation — Working with Individual Samples

One of the main features of OptiSystem is the mixed signal representation. Individual sample is a signal type that allows the users to simulate time-driven systems in the electrical and optical domain. By using time-driven simulation, users can create designs that have closed loops and feedbacks. Additionally, the optical individual sample allow for simulation of…

Lesson 7: Optical Amplifiers — Designing Optical Fiber Amplifiers and Fiber Lasers

OptiSystem allows the design and simulation of optical fiber amplifiers and fiber lasers. The projects presented here are available under OptiSystem installation folder samples\Optical amplifiers. This tutorial will describe part of the library of optical amplifiers. There are four categories of components in the library: EDFA Raman SOA Waveguide amplifiers The EDFA folder contains the…
