For the first time, up to 160 Gbaud 16-QAM and 8-PSK transmission over graded-index multimode fibre is demonstrated using optical time division multiplexing and de-multiplexing in combination with coherent detection.
An optical parametric amplified (OPA) fiber switch is described in this paper. This device switches input signals without shifting the wavelength by changing the polarization state of the signal using optical parametric amplification. The OPA fiber switch features ultra-broadband, highly efficient switching with a high contrast ratio. We experimentally test the prototype of the OPA fiber switch, which...
We experimentally investigate the switching performance of interferometric gates based on highly nonlinear fiber (HNLF), a Kerr-gate and a nonlinear optical loop mirror. Switching windows are measured and compared for different operation conditions and HNLFs
