Liquid Crystal Light Valves Driven by Photovoltaic Fields: Continuation
Abstract
The results are promising to create reconfigurable diffractive samples and holograms in a thin layer of liquid crystal via the controlled exposure to light. The control of laser generated defects is essential for this purpose and this goal has been achieved, successfully. The ongoing work now focuses on control of the writing setup (movable sample vs. scannable beam) and improved exposure quality. In addition, Light valving (quickly redirecting light) was investigated in samples where the optical axis of the substrates was in plane and the optical axis of a nematic LC was (initially) aligned perpendicular. These samples could be switched from a dark state to a transmissive state, efficiently. The field induced (light induced) director reorientation was understood in detail.
