All-Optical Wavelength Conversion at 40 Gb/s Data Rate in Silicon Waveguides
ABSTRACT We report efficient wavelength conversion of a high speed signal at 40 Gb/s via four-wave mixing in silicon-on-insulator rib waveguides. Results give an efficiency of -8.6 dB, and the converted signal shows good signal integrity.

ABSTRACT: We report our recent studies on nonlinear processing of optical signals using a 35-cm highly nonlinear bismuth oxide fiber (Bi-NLF). Our findings are based on self-phase modulation, cross-phase modulation, and four-wave mixing in the Bi-NLF. We demonstrate applications of the nonlinear techniques in optical signal regeneration, tunable optical delay, stabilization of multiwavelength laser source, tunable optical pulse generation, microwave photonic carrier frequency multiplication, and all-optical wavelength conversion.IEEE Journal of Selected Topics in Quantum Electronics 06/2008; DOI:10.1109/JSTQE.2008.915523 · 3.47 Impact Factor
