Large-core, broadband optical fiber.
A broadband optical fiber with larger core diameter than that of a conventional single-mode fiber is proposed. By appropriately choosing normalized frequency v = 4.6 and core profile parameter alpha = 4.5, a core diameter as large as 16.3 microm with relative index difference Delta = 0.3% at the 1.25-microm wavelength is attainable. Fabrication tolerances, bandwidth, and bending loss of the fiber are discussed.
