Reconfigurable Delay Time Polymer Planar Lightwave Circuit for an X-band Phased-Array Antenna Demonstration
TL;DR: In this article, a 4-bit polymer optoelectronic true-time delay (TTD) device is demonstrated, which is composed of monolithic integrated low-loss passive polymer waveguide delay lines and five cascaded 2 times 2 polymer thermooptic switches.

Fringing-field minimization in liquid-crystal-based high-resolution switchable gratings
TL;DR: In this paper, a double-sided liquid crystal (LC)-based high-resolution switchable grating is proposed by using a doublesided structure, where striped electrodes are patterned on both sides of the LC cell.

2-bit reconfigurable true time delay lines using 2/spl times/2 polymer waveguide switches
TL;DR: In this article, a 2-bit (four delays) polymer waveguide delay device is demonstrated and characterized, which is composed of polymer delay lines, optical fiber delay lines and polymer thermooptical 2/spl times/2 switches.

Phase error corrected 4-bit true time delay module using a cascaded 2 × 2 polymer waveguide switch array
TL;DR: A fully integrated 4-bit true time delay device using polymer optical switches and waveguide delay lines is demonstrated and the rf phase error is theoretically analyzed and proved to be negligible by experimental results.
