Paper Abstract

In the past, an array illuminator (AIL) consisting of a so-called Talbot plate was mainly considered for concentrating coherent light onto the active areas of an array of micro-electrooptic components 1. A Talbot plate commonly consists of a one-dimensional multilevel phase grating and transforms at certain distances, called the fractional Talbot distances, a plane wave into an array of light stripes with a duty cycle (DC) of equal or less than 50% 2. The Talbot distance itself is defined as = 2D2 / X where D denotes the grating pitch and X is the optical wavelength.
