User Guide

The File Menu When you start OptiGrating, you have only three menus to work with: File, View, and Help. However, when you create a new project or open an existing one, you notice that there are nine menus that contain all commands you will need to do your work effectively. The File menu, shown on…

File: New > Single Fiber The Single Fiber Module You use the Single Fiber module to model a fiber with arbitrary radial symmetry while the grating can be placed anywhere in the fiber. OptiGrating allows you to adjust both the fiber dimensions and refractive index profile and photosensitivity profile. You can simulate the grating assisted…

File: New > Fiber Coupler The Fiber Coupler Module You use the Fiber Coupler module to model two fibers embedded in one infinite cladding. The grating can be placed anywhere in the coupler. OptiGrating allows you to adjust both the fiber coupler dimensions and refractive index profile and photosensitivity profile. You can optimize the coupling…

File: New > Single Waveguide The Single Waveguide Module You use the Single Waveguide to model a multilayer slab waveguide with grating. The grating can be placed on the interface of layers as surface relief grating, or in layers as index-modulated grating. You can simulate the coupling between forward and backward propagating modes. There are…

File: New > Waveguide Coupler The Waveguide Coupler Module You use the Waveguide Coupler Module to model a two slab waveguide with a grating. The grating can be placed on the interface of layers as surface relief grating, or in layers as indexmodulated grating. You can simulate the coupling between modes of the two waveguides.…

File: New > Other Waveguide The Other Waveguide Module You use the Other Waveguide Module to model general waveguides with a grating. In this module, the user needs to define the mode properties instead of the waveguide profile in the other modules. The Other Waveguide module finds application in WDM add/drop filters, Bragg gratings, Long…
