Description
  • We have developed a data transparent optical packet switch, working at optical powers conventional in telecommunications. Polarization sensitivity of only 0.6 dB was achieved. The optical packet switch exploited wavelength conversion based on four-wave mixing. To achieve higher switching efficiencies, Ge-doped silica suspended-core and chalcogenide arsenic-selenide singlemode fibers were employed and compared to conventional highly-nonlinear fibers. Improved connectorization technology has been developed for both fibers to reduce overall component insertion loss, where we achieved connection losses of 0.9 dB. For the arsenic-selenide fiber we present the lowest attenuation up-to-date of 0.58 dB/m. Pump power limits for optical packet switching were set to 23 dBm, as limited by most thin-film components. Conversion efficiency of -16 dB was obtained for the highly-nonlinear fiber utilizing pump peak powers of 16 dBm. Arsenic-selenide fiber of 26 m length was evaluated, providing conversion efficiency lower than -38 dB with component insertion loss of -16.5 dB, thus further optimization was carried out according to simulated results. Conversion efficiency of -20 dB was observed with arsenic-selenide fiber length reduced to one meter.
