Phase Steps - Mode Converters

Phase plates with linearly shaped phase steps are commonly used as mode converters and allow to transform Laguerre-Gaussian Modes from TEM00 to higher modes TEM01, TEM11 etc. Such transformations are applied for example in the field of optical cavities and resonators, optical tweezers, atom and molecule excitation. Those phase plates have a physical step on the surface with a height corresponding to a phase shift of π/2. This difference in the optical path leads to a destructive interference in the step region and resulting zero intensity in the beam profile.
