利用奈米全像液晶聚合物薄膜（holographic polymer dispersed liquid crystal, HPDLC）作為二維光子晶體來驗證具偏振的超稜鏡現象。實驗上由三道同平面雷射光干涉，將干涉強弱分佈紀錄在液晶聚合物薄膜，形成HPDLC薄膜，具有二維有序的奈米液晶區域（直徑約為150nm）散佈在聚合物中，且利用SEM影像估計其週期約為350nm。實驗結果確認具有超稜鏡現象，白光色散可逹50°左右，且與入射光之偏振有關，理論上經由平面波展開法與實驗上HPDLC超稜鏡分光出的偏折光加以印證，結果發現實驗結果與理論相符。

　Polarization dependent superprism phenomenon was demonstrated using nano-sized holographic polymer dispersed liquid crystal (HPDLC) films. Experimentally, the HPDLC film was designed and fabricated using three coplanar interference beams. The fabricated HPDLC film contained two-dimensional (2D) ordered nano-sized LC domains (~150nm in diameter) embedded in polymer matrix; its periodicity was estimated to be 350nm under scanning electron microscopy. Superprism effect was confined using HPDLC photonic crystal. The deflection of a white light from HPDLC superprism was about 50°.The deflection of output light from the HPDLC superprism was compared and consistent with the theory based on the plane wave expansion method.
