Modeling of Low-Loss IR Transmitting Fibers, Sourcesm and Detectors
Abstract
Near- and mid-IR light has a wide range of potential applications that both non-military applications like environmental and medical sensing, as well as military applications such as IR countermeasures and laser threat-warning systems. While silica-based optical fiber technology is highly developed and allows great control over the fiber fabrication, losses in these fibers grow rapidly in at wavelengths longer than 2.5 µm, which makes them impractical for applications beyond 3.0 µm. Conversely, other glasses like chalcogenides have losses that remain low up to 10µm in some cases, it is more difficult to control the fiber fabrication. Thus, the research effort focuses on theoretical and computational work to optimize the design of the negative curvature chalcogenide fibers for low loss of the fundamental mode, and to determine the sensitivity to losses when there are fabrication flaws. This research effort proposes to theoretically and computationally examine the trade-off between higher power and loss for mid-IR materials as compared to chalcogenide fibers in new negative curvature fibers.
