Abhishek Kumar Srivastava received his Ph.D. degree in 2008 from the University of Lucknow, Lucknow, India, for the dielectric and electro-optical study of guest host mode ferroelectric liquid crystals. Just after his Ph.D. he joined the Optics Department of Telecom Bretagne, France as a post-doctoral fellow. At Telecom Bretagne he worked on active liquid crystals shutters, liquid crystal composites and their dielectric and electro-optical characterization. In 2009 he has been awarded by the young scientist fast track fellowship from the Department of Science and Technology of the government of India. Currently, He is working as research associate at Hong Kong University of Science and Technology, Hong Kong. His current research interest includes photoaligned ferroelectric liquid crystals for advanced displays and photonic devices. To date he has published 44 research papers in highly reputed journals and holds 5 patents/patent applications.
The optical texture of a ferroelectric liquid crystal cell having two orthogonally aligned domains in 2D. The regular dual alignment pattern (the small, roughly circular, domains are about 30 microns in diameter) has been created by means of photoalignment, see article in Applied Physics Letters for full details. The texture was captured with an Olympus BH3 MJL polarizing microscope and a Sony CCD-IRIS camera.
