Abstract
A multicore optical fiber is provided including a first core region having a first refractive index profile, a second core region having a second refractive index profile, wherein the first core region is separated from the second core region by a separation distance in a range of 20-50 μm, and an outer cladding surrounding the first and second core regions, wherein the first core region exhibits a first effective index and a first group index and the second core region exhibits a second effective index and a second group index, and the first and second effective indices are substantially different to suppress crosstalk and the first and second group indices are substantially the same to achieve a substantially similar group velocity.
