Fabrication of two-dimensional fiber arrays using microferrules

A two-dimensional (2-D) PANDA/multimode fiber array using microferrules was fabricated for use in photonic switching modules. This 250-/spl mu/m pitch 8/spl times/8 fiber array (a channel density of 16/mm/sup 2/) had an average fiber position error of 2.25 /spl mu/m, and crosstalk of less than 20 dB for beam traveling distances of 30 mm.
