Patent number: 7408601Abstract: Inhomogeneous concentrated polymer network with approximately 90° twisted nematic liquid crystal (TN-LC) is used for fabricating lens and prisms. For forming a positive lens, the approximately 90° TN-LC polymer network concentration can gradually decrease from the center to the side edges. For forming a negative lens, the approximately 90° TN-LC polymer network concentration can gradually increase from the center to the side edges. The lens can be created by ultra violet (UV) light exposure to patterned photo masks. The lens can be tuned by applying voltage above the threshold voltage to the polymer network. The inhomogeneous 90° TN-LC polymer network can also be used in Fresnel lens and prisms. Applications of the invention can be used for micro lens, array, optical communication, micro-optics, adaptive optics and beam steering.Type: GrantFiled: December 9, 2005Date of Patent: August 5, 2008Assignee: Research Foundation of the University of Central Florida, Inc.Inventors: Yuhua Huang, Hongwen Ren, Xinyu Zhu, Shin-Tson Wu
