Design and Study of Optical Devices Based on Holographic Polymer Dispersed Liquid Crystal Technology
Micro/nanoscale liquid crystal (LC) droplets are dispersed within polymer matrix, known as polymer-dispersed liquid crystals (PDLCs). LC molecules can be reoriented under an applied voltage, which makes PDLC-based devices have wide applications in optical communications, integrated optics, and panel displays, etc. In this paper, we summarized our work on holographic PDLC (H-PDLC) devices including variable attenuators, dynamic gain equalizers and focus-switchable lenses. More importantly, a specially designed H-PDLC chopper array was demonstrated, which will be applied in the new-born frequency division multiplexed high-speed fluorescence confocal microscope system.
