Abstract

A methodology for designing an octic-style optical true-time-delay (TTD) device based on the White cell (WC) is investigated. The octic cell is a "polynomial" cell, one of the two classes of TTD White cells. This octic cell is designed to produce a maximum of 6399 delays in 17 bounces, with a unit delay of 3 ps. Glass blocks are used for short delays, white lens trains are used for the longer delays. The octic cell is designed to use a microelectromechanical tip/tilt micromirror array to direct light beams into various delay paths.
