We propose a transponder-independent metric that can uniquely describe the performance of dispersion uncompensated links. Derived from OSNR and performance measurements using an available transponder, it can be used for performance prediction of any other transponder on the optical path.
Based on the first prototype, a newly modified trigger multiplexer module (merger) is under development for the Central Drift Chamber (CDC) detector which will be used in the future Belle II experiment. The features of modified merger circuit board include two Arria II FPGAs, four 3.125G optical modules and one 6.25G optical module for data transmission. The modified circuit board of merger was made...
A compact and efficient control plane has been implemented to demonstrate multipath routing for a twenty-electrode photonic integrated circuit with round-robin scheduling. A single slot clock with 3.2 μs packet period dynamically cycles connections between all input and output ports.
We demonstrate using single-sideband-carrier-suppressed (SSB-CS) signal to suppress the Rayleigh-Backscattering (RB) in a carrier-distributed PON. The SSB signal is generated by a dual-parallel Mach-Zehnder modulator (DP-MZM). The split-ratio and reach are also investigated and analyzed.
We have studied the dynamics and stability of solitonic pulses (including soliton interaction) across URFL transmission links, as well as the dependence of these dynamics on cavity design (length, symmetry, reflectivity) and input pulse characteristics. The first experimental demonstration of long-distance ldquotruerdquo soliton propagation through optical fibre. The results conclude that even relatively...
In this scheme, nonlinearity and dispersion in the NDF lead to various reshaping processes of an initial, conventional pulse according to the chirping value and power level at the input of the fibre. In particular, we have observed that triangular-shaped pulses can be generated for sufficiently high energies and a positive initial chirp parameter. In our experiments, 2.8 ps-FWHM, transform-limited...
A novel Quantum Dot monolithically integrated 1×8 switch is shown to provide robust routing of data at 10Gb/s modulation rates. Two cascaded switches providing, 1×64 functionality, operate with a power penalty of only 0.9dB.
To meet the ever-increasing demand of data and mobility of access networks, we demonstrate a hybrid-wire/wireless network, using 10Gb/s NRZ and 10Gb/s OFDM signals. 1-dB power-penalty was observed in 25km single-mode-fiber transmission without dispersion compensation.
10Gb/s error-free operation of the first monolithic 16×16 quantum well semiconductor optical amplifier switch is demonstrated. The switch has a 2dB facet-to-facet gain and a minimum power penalty of 2.5dB.
We present the first experimental demonstration of true (not loss managed) soliton pulse transmission in conventional optical fibre. Experimental FROG spectrograms and numerical simulations confirm the soliton pulse evolution dynamics.
