We propose a scheme enabling direct serial-to-parallel conversion of OTDM data tributaries onto a WDM grid, based on optical Fourier transformation with spectral compression. Demonstrations on 320 Gbit/s and 640 Gbit/s OTDM data are shown.
A compact ultra-wideband (UWB) filter is designed by a proposed stepped impedance dual-mode resonator. The dual-mode resonator is formed by adjusting the impedance ratio. There are four resonant modes inside pass-band of the novel filter, two of which are generated by dual-mode resonator and the other two modes are produced by parallel-coupled feed lines. This results in the formulation of the novel...
Error free and low penalty generation and detection of 2.56 Tbit/s serial data is demonstrated. 1.28 Tbaud pulses are modulated with DPSK and polarisation multiplexed to achieve 2.56 Tbit/s with record low penalty.
We present a single-channel 1-Tb/s transmission system based exclusively on semiconductor pulse sources. By using alternating polarization RZ-DQPSK modulation a record transmission length of 480-km dispersion managed fiber is achieved.
