Paper Abstract

We report on two new computer generated hologram (CGH) elements for optical processing. They are a one-to-many optical interconnection element (that allows analog weights, high efficiency, and is not restricted to a regularly spaced grid) and an element to provide separate 1-D collimation of the laser diodes in an array (with high efficiency). Error diffusion encoding and multilevel phase CGHs are used to achieve high accuracy and high efficiency. Simulations are used to show the advantage of error diffusion (ED) encoding. Optical laboratory data are included to show the feasibility of the elements and the validity of our simulator.
