Diffractive optics has become an indispensable technology in many fields to the point where nowadays it is applied in medical applications as well. One example in this field is the intraocular diffractive lens, which is implanted in the eye for the treatment of cataracts or myopia. The diffractive lens, together with the original human eye structures, makes a hybrid lens system. With VirtualLab Fusion, we show how to model and design such systems, particularly with the workflow that supports the import of Binary 2 surfaces from Zemax OpticStudio®.Read more
A resonant waveguide grating, which is made up of a thin waveguide film in contact with a grating, shows great potential in different applications due to its high optical tunability. With the Fourier modal method (FMM, or RCWA) in VirtualLab Fusion, we analyze the response of such gratings. In the example below, the parameter coupling feature is used to help define the parameters under investigation in a relative manner. Furthermore, the resonant modes within the grating structures are computed as well to study the working principle of such devices.Read more
Ultrashort pulse lasers, with time duration in femtoseconds, are of great importance and potential for both fundamental research and industrial applications. For example, such lasers enable the extremely precise processing of materials, which is known as “cold” ablation. In VirtualLab Fusion, an ultrashort pulse is modeled as a composition of a broadband spectrum, and the correlation between the different spectral modes is considered. That enables the investigation of ultrashort pulse behavior in both spatial-temporal (or spatial-spectral) domain, as shown in the examples below.Read more
Learn from our optical engineering experts how to use VirtualLab Fusion efficiently. Register for both courses or only one, depending on your previous experience working with VirtualLab Fusion.
Since numerous new features are included in our VirtualLab Fusion Winter Release 2019, these courses would be interesting for current users as well.
