We experimentally demonstrate interplay between PMD and nonlinearity in 112 Gb/s DP-QPSK signal transmission with 10.7 Gb/s NRZ neighbors can have both positive and negative impact depending on channe...
A novel parallelized implementation of the split-step Fourier method on graphics processing units was developed. The combination of Monte-Carlo simulations with single and double precision yields a sp...
We derive closed-form expressions depending on a single fitting parameter for performance prediction of WDM PM-QPSK long-haul uncompensated transmission. Besides general properties, we demonstrate tha...
We analyze chirp techniques for suppression of nonlinear effects in DP-QPSK transmission. Simulations reveal that a significant reduction in nonlinear polarization scattering can be achieved by proper...
We investigate transmission performance for 112 Gb/s PM-QPSK DWDM systems over NZ-DSF with configurations enabled by NZ-DSF dispersion characteristics. We find flexibility in dispersion compensation f...
We study transmission of 40 Gb/s signals using coherent RZ-QPSK with and without polarization multiplexing using 100km large effective area fiber-spans and dual-stage EDFAs with mid-stage dispersion c...
We experimentally study the performance of an economically-viable, high-capacity supercomputer optical interconnect employing wavelength-space optical packet switching,polarization division multiplexe...
We report the transmission of 155 channels with 100Gbit/s PDM-QPSK modulation over 7200km of pure silica core fibre, exploiting hybrid Raman-EDFA amplification and digital coherent detection. A record...
We compare the nonlinear limits of 42.7 and 85.4 Gb/s PDM-QPSK transmission. Intra-channel nonlinearity compensation is demonstrated, with increase of optimum launch power by 1dB in each case and corr...
We demonstrate the first mid-infrared free-space optical link employing coherent detection and parametric wavelength conversion.
We demonstrate joint polarization carrier phase estimation for XPM-limited channels with significant improvements over standard methods, demonstrated on measurements of 43Gb/s NRZ-CP-QPSK with 10.7Gb/...
