Phase Steps - Mode Converters

Phase plates with linearly shaped phase steps are widely used as mode converters, transforming Gaussian TEM₀₀ beams into higher-order modes such as TEM₀₁ and TEM₁₁. These transformations are used in applications including optical cavities and resonators, optical tweezers, and atomic and molecular excitation. Each plate has a physical step machined into its surface, with a height precisely tuned to introduce a phase shift of π between the two halves of the transmitted beam. This optical path difference causes destructive interference along the step, producing a sharp zero-intensity line that splits the beam profile into distinct lobes.
