Microlens arrays can be found in different applications, such as imaging, wavefront sensing, and so on.
With the physical-optics simulation technique in VirtualLab, the working principle of the microlens array, e.g. in the case of wavefront sensing, can be clearly demonstrated, and the performance of such systems can be evaluated efficiently. It is also worth mentioning that the diffraction effect from the edge of the individual microlenses can be taken into consideration in the simulation.
How to ensure a high-efficient coupling of light into optical fibers is an important question in all fiber-related applications.
In VirtualLab, the focal field behind the coupling lens can be easily calculated with the fast physical optics simulation engine, and by calculating the overlap integral, the fiber coupling efficiency can be evaluated. Additionally, with the parametric optimization, the lens parameter can be optimized for customized situations.
It is vital in design to be able to include in your simulation not only those properties or components that play an intentional, wanted role in the system, but also, and with particular care, those effects which have the potential to interfere with its intended purpose, in order to quantify and, if possible, avoid them.
Below we show two examples of VirtualLab’s potential in this area: all thanks to its fast and accurate approach, and an interface that allows you both to import measured data (from, e.g., ANSYS) or to include the effects via readily available or customized mathematical models.Read more
Graded-index, or GRIN, media are employed in optics to construct, among other components, lenses and multimode fibers. In VirtualLab you can easily choose to GRIN media as part of your optical system, as it includes a fast and accurate modeling technique accompanied by a user-friendly interface that makes setting up the GRIN component a really easy task.

It is of importance to understand how the field is evolving during the propagation through the focal region along the optical axis.
In VirtualLab Fusion, with the Parameter Run, it is possible to perform a scan of the field along a succession of planes, and thus to have access to the complete information of the electromagnetic field inside the focal region. Particularly, all eventual vectorial effects due to high-NA focusing are taken into account.

Lasers and laser systems play an indispensable role in modern life. They can be found in various applications such as laser material processing, metrology, monitoring, lighting, and so on. Physical-optics based modeling techniques are necessary for the successful design and analysis of a laser system. With its second-generation field tracing technique, VirtualLab constitutes a suitable tool to perform an efficient evaluation of laser systems. We demonstrate, as examples, the collimation of a laser diode with astigmatism and a laser scanning system.Read more
