Abstract

A 16-ch × 16-ch optical full-cross-bar connection module is demonstrated by fabricating an optical cross connector to configure a cross-bar connection, a 16-ch two-dimensional push/pull receptacle-type vertical-cavity surface-emitting laser (VCSEL) array module, and a 16 × 1 ch plug-type coresize-conversion polymer-waveguide coupler connector. This configuration makes an all-optical space-division switch possible using simple, compact and low-cost components. The fabricated VC-SEL module exhibits an insertion loss of 2.1 ± 0.8 dB, and the coupler connector with the cross connector exhibits an insertion loss of 4.6 ± 0.3 dB. The resulting total loss of 6.7 ± 1.1 dB from VCSEL to fiber output after the cross-bar connection is sufficiently low to apply for an optical network switch.
