Abstract

The use of polarization selective holograms for the implementation of photonic delay lines (PDLs) is proposed. A single bit PDL using FLC devices as active polarization switches and polymer dispersed liquid crystal (PDLC) devices as polarization selective optical path routing components is experimentally demonstrated and characterized. Different within-channel leakage noise filters are discussed and experimentally demonstrated, and high signal-to-leakage noise ratios (>45 dB) are obtained for both PDL settings.
