ITERATIVE DESIGN OF BINARY AND QUANTIZED DOE
TO FOCUS INTO A DESIRED DOMAIN

Purpose:
simplified technology of fabricating high-efficient DOEs
Benefits:
easy to fabricate by photolithographic methods, high energy efficiency (~80%) and low rms error.

Phase of a binary DOE to focus into a ring

Phase of a binary DOE to focus into the letter “Н”

Phase of a binary diffraction grating with 33х33 orders

Phase of a DOE with four phase levels to focus into the letter “F”

Intensity distribution in the focal plane:
