New Optical Rewritable Electronic Paper

The idea of electronic paper is to store and display information generated by computer on a lightweight thin, flexible, and robust paper-like carrier with good 

Possible but not limiting applications of the new e-paper based on photoaligning are lightweight printable rewritable paper, labels, and plastic card displays, as well as rewritable 3D paper for security applications and overhead projection including building designs, various 3D outline sketches, and maps. 

Poor LC alignment on the uneven surface of a photonic chip is one reason for the considerable reduction in the overall LC refractive index change in the cladding under an external electric field and for consequent inefficient operation of the LC photonic device [27], This problem can be overcome when a thin 12-14 nm 

LC alignment on Si surfaces with submicrometer-sized straight and curved waveguide profiles has been smdied [28, 29]. The LC cladding refractive index was varied by an applied voltage, and subsequently the microresonator resonance
