Optical beams with orbital angular momentum (OAM) have proved useful for different applications, from quantum optics to optical telecommunication and to microscopy. Different methods have been proposed for the generation of such beams and here we demonstrate, in VirtualLab Fusion, how to use a spiral phase plate to generate beams carrying OAM. A programmable interface is used to describe the spiral phase plate with customizable parameters, and the microstructure component is used for its modeling.

he construction of optical systems combining diffraction gratings and lenses and other smooth surfaces is a common occurrence. We have selected three examples to illustrate in the webinar the potential of VirtualLab Fusion in this field.

In order to adapt to different time zones worldwide, we will hold this webinar twice (all times CEST):

Can a microlens still focus light as expected when the pixel size edges closer to the wavelength? We investigate this issue with VirtualLab Fusion at selected examples.

By continuously decreasing the pixel size of CMOS sensors, better and better spatial resolution has been achieved in recent decades, with the tendency expected to continue. This, however, turns the spotlight onto the microlenses sitting on top of each pixel. Can a microlens still focus light as expected when the pixel size edges closer to the wavelength? We investigate this issue with VirtualLab Fusion at selected examples.
