WebIn optical computing machines, many parameters of light beams can be used as data carriers. If the data are carried by optical vortices, the information can be encoded by the vortex topological charge (TC). Thus, some optical mechanisms are needed for performing typical arithmetic operations with topological charges. Here, we investigate the … WebNov 3, 2024 · Hello, I'd like to ask a few questions about plane wave expansion method in the wave optics module and some general questions. How does Comsol deal with the paraxial Gaussian beam when the beam waist is very small? According to the equations in the User's guide (pages 154-155), there is an explicit result for the amplitude of the …
