Exploring the Fundamental Mechanisms of Light Modulation and Amplification in Halide-perovskite Nanostructures
Abstract
Naval relevance and contribution to the ONR and Department of Navy mission:Enabling robust long-range high-bandwidth underwater optical communications (UWOC) is one of the priorities of Integrated Research Portfolio - Undersea Battlespace and Maritime Domain Sensing. Ability to transmit and receive significant amount of data underwater reliably and covertly is essential for development of distributed and networked underwater sensors, unmanned and autonomous underwater vehicles, undersea signal processing, and diver operations. There is no alternative to UWOC in these applications because underwater acoustic communications suffer from limited bandwidth and vulnerability to detection and interception. Development of the free-space optical communications devices with properties that are tailored to specifics of underwater environment is critical to increasing the bandwidth and expanding the reach of UWOC.Principal challenges of underwater optical communication are scattering that limits communication range; difficulty of transmitter-receiver alignment (caused by typical underwater CONOP and underwater turbulence) that reduces communication link quality and ability to connect in general; and SWaP restrictions inherent to operation underwater. Proposed program addresses these challenges from the device physics standpoint by enabling amplification of light signal underwater, by relaxing requirements on transmitter-receiver alignment, and by reducing SWaP of the UWOC equipment.
