Abstract: We demonstrate the fabrication of a large scale device allowing for electrical switching of polarized light with a polarization ratio of 0.45 over a 1.5 cm2 area. To achieve this, silica coated semiconductor nanorods were embedded in polymeric nanofibers by electrospinning. The uniaxial extensional flow experienced by the particles induces alignment of the nanorods within the nanofibers. A subsequent parallel alignment of the nanofibers themselves results in a large and flexible film of massively aligned nanorods that can conveniently be processed further. We demonstrate this by integrating the aligned nanofibers in a liquid crystal cell with a polarizer where applying a voltage allows switching the emitted light on and off.
