In this study we demonstrate a monolithic liquid crystal (LC) diffraction grating with multiple diffraction modes using the techniques of polymer stabilization and novel electrode design. It can be applied to a single-path rewritable optical pick-up (OPU) with multiple wavelengths for the tracking compatibility of CD, DVD, and blue-light storage systems.
