Abstract
Optical fibers having a large effective area and a low cutoff wavelength are disclosed. Three main embodiments of the optical fiber allow for single-mode operation at wavelengths greater than 980 nm, and have a large effective area with low bend losses and low dispersion at 1310 nm. The large effective area optical fiber is expected to be particularly useful for data center applications due to its ability to efficiently optically couple with VCSELs and photonic integrated devices. Integrated systems and optical communication systems that employ the optical fibers are also disclosed.
