This paper addresses the problem of anti-windup design for linear systems subject to both actuator magnitude/rate saturation and to sensor saturation. Anti-windup design procedures are developed, using both measured and estimated variables, which allow the region of stability of the closed-loop system to be enlarged. The results are derived by modelling the saturated system as a linear system with...
We report continuous-wave wavelength conversion from the telecom band to the mid-infrared via four-wave mixing in silicon nanowaveguides. We convert a 1636-nm signal to produce a 2384-nm idler, demonstrating a parametric bandwidth of 748 nm.
We demonstrate for the first time four-wave mixing based wavelength conversion of phase modulated optical signals in dispersion-engineered silicon waveguides. Error-free operation and 1-dB power penalties are experimentally obtained for 10-GB/s DPSK wavelength-converted signals.
We demonstrate an increase of nearly 10 dB in the efficiency of broadband wavelength conversion via four-wave mixing in silicon nanowaveguides by incorporating a p-i-n structure and applying modest voltages to remove the free carriers.
We demonstrate broadband continuous wavelength conversion of 10-Gb/s data across 100 nm using four-wave mixing in dispersion-engineered silicon waveguides. Error-free operation and constant 2-dB power penalties are experimentally obtained for all examined probe-idler separations.
Data fidelity is inspected for the first time for wavelength-converted RZ TDM 80- and 160-Gb/s data using four-wave mixing in a silicon waveguide. Open eye diagrams and error-free operation is shown for demultiplexed 10-Gb/s tributaries.
