Programming C# Modules
The customization potential of the optical modeling and design software VirtualLab Fusion is nowhere more evident than in the modules. While most other programmable items in the software present the logical constraint of pre-defined inputs and outputs, the modules (be they coded in C# or Visual Basic) offer the user total freedom of implementation. Below, we present an in-depth tutorial describing the basic workflow for how to program and use your own modules, with a simple example given in detail as illustration. We include a second, more advanced example in a more condensed format.
How to Work with the C# Module and Example
Learn how to program and work with your own custom C# modules in VirtualLab Fusion with this detailed tutorial.
Programming a Module that Smooths the Edges of a Structure
This C# module has the very specific purpose of being used for a tolerance analysis of fabrication errors: taking as input the designed profile of a diffractive element, it rounds off the ideally sharp edges to attain a more realistic configuration.

Fiber-Coupling Lens Design and Tolerance Analysis
In many fiber-optics systems, a customized design of the coupling lens is often required so as to achieve a good fit with the given input field and working distance. VirtualLab provides not only the tools for the analysis of fiber-coupling efficiency, with the in-built Parametric Optimization function, but also enables an efficient design of the coupling lenses. In fiber optics, it is also known that coupling efficiency may be sensitive to e.g. misalignment of the components in the system. With the Parameter Run in VirtualLab, one can conveniently perform a tolerance analysis of such fiber-coupling systems and investigate the influence of different parameters.
Parametric Optimization of Fiber-Coupling Lenses
We present the design of a fiber-coupling lens with conical surface, for the purpose of efficient light coupling into a single-mode fiber, using parametric optimization in VirtualLab Fusion.
Tolerance Analysis of a Fiber-Coupling Setup
In a fiber-coupling optical setup, the coupling efficiency is analyzed with respect to different tolerance factors like the shift of the position of the fiber end and the tilt of lens.

Programming Custom Detectors
In some of our previous newsletters we already spoke of the potential for customization via programming, which is characteristic of the optical modeling and design software VirtualLab Fusion. In the current newsletter we present another programmable element: detectors. Full accessibility to the vectorial electromagnetic field, paired with the customizability, further increases versatility, facilitating the implementation of any detector function. Find below two documents that illustrate how to work with the Programmable Detector in VirtualLab Fusion: a detailed tutorial and an additional example in a more condensed format.
