Using Diffractive Optical Elements [PDF]
Optik & Photonik, 2018 AbstractA diffractive optical element (DOE) uses thin micro‐structure patterns to alter the phase of the light that is propagated through it. Those micro‐structures, once properly designed, can manipulate the light to almost any desired intensity profile or shape.

Nonlinear Diffractive Optical Elements
Optics Express, 2007 We propose diffractive optical elements with a spatially-varying nonlinear refractive index. Such a component acts as a diffractive optical element whose properties depend on the intensity of the incoming beam. We present a method for designing such elements, and as specific examples we study three types of nonlinear diffractive optical elements ...
