Error-free demultiplexing from 160 to 10 Gb/s is demonstrated.endemultiplexing equipmenthigh-speed optical techniqueslight interferometersnonlinear opticsoptical fibre communicationoptical fibre polarisationsemiconductor optical amplifierssensitivitygb/s polarization insensitive all-optical demultiplexinggain-transparent ultrafast nonlinear interferometerpolarization-insensitive all-optical demultiplexergain-transparent operationsemiconductor optical amplifierultrafast nonlinear interferometerpolarization diversityerror-free demultiplexing160 to 10 Gbit/s621535160-Gb/s polarization insensitive all-optical demultiplexing using a gain-transparent ultrafast nonlinear interferometer (GT-UNI)journal article
