The GT-UNI comprises a robust fiber-chip setup in a novel, folded geometry. For switching window widths of 5.2 ps and 6 ps error-free demultiplexing of 160 Gb/s to 10 Gb/s is demonstrated.endemultiplexingdemultiplexing equipmenthigh-speed optical techniquesintegrated opticlight interferometersoptical communication equipmentoptical modulationoptical switchphase modulationsemiconductor optical amplifiertime division multiplexingall-optical demultiplexergain-transparent soa operationultrafast-nonlinear interferometerrobust fiber-chip setupfolded geometryerror-free demultiplexingotdmcross phase modulation switch160 Gbit/s621conference paper
