Abstract
Wide field of view (FOV) free space optical communication systems (FSOCs) have gained attention due to their potential for enhanced data transmission and expanded coverage. These systems can use volume holographic optical elements (HOEs) for their narrow filtering. However, HOE filtering characteristics depend on the substrate thickness, limiting the FOV for thicker substrates. Multiplexing can enhance the FOV but reduces the refractive index modulation. To overcome these limitations, we propose a novel method that involves writing plane wave beams to a hollow cylindrical substrate, thus doubling the FOV. Experimental and theoretical results support this approach, offering the potential for 360° panoramic FSOCs.
