Polarization maintaining fiber array with increased polarization extinction ratio and method of making
A polarization maintaining fiber array includes a substrate, a cover, and at least two polarization maintaining optical fibers. The substrate includes at least two main grooves, a first additional groove, and a second additional groove, wherein the main grooves are positioned between the first additional groove and the second additional groove. The fiber array includes at least two polarization maintaining optical fibers positioned in the at least two main grooves, a first dummy fiber positioned in the first additional groove, and a second dummy fiber positioned in the second additional groove. The cover is positioned such that it contacts the polarization maintaining optical fibers, the first dummy fiber, and the second dummy fiber.
