Diffractive optics

Making use of diffraction phenomena to obtain the desired pattern of light is the working principle behind beam splitters, spatial light modulators (SLMs) and many other optical elements. VirtualLab Fusion puts the tools at your disposal to, among others,

  • take advantage of a guided, user-friendly design concept
  • optimize high-NA beam splitters to eliminate distortion
  • analyze the effect on the overall target beam of diffraction phenomena at individual pixels of an SLM
  • investigate the combination in a general system of the diffractive optics with other optical components (like real lenses)
  • export fabrication data of the designed element
  • design beam splitters for arbitrary target patterns

Selected Use Cases

Find detailed technical information in the following selected samples:

Design and analysis of a diffractive beam shaper to transform a Gaussian beam into a doughnut mode through manipulation of the phase. 

A beam-splitting element is designed and optimized for an arbitrary target pattern. 

Flexible export of fabrication data for smooth and quantized surfaces, as well as for mirror, prism and grating cell arrays. 

Investigation of the combination of a Spatial Light Modulator (SLM) with a series of real lenses. The effect of the different lens aberrations on final quality is studied. 

Investigation of the effect of pixel gaps on performance of a spatial light modulator (SLM).
