All-fiber single-pulse selection and nanosecond gating.

Two functions normally attributed to Pockels cells are performed with internal-electrode microstructured fiber components. Single-pulse selection out of a 100 MHz mode-locked pulse train is demonstrated using all-fiber nanosecond polarization rotation. Additionally, off-on-off gating with duration approximately 13 ns is achieved with a polarization rotator made out of a four-hole silicate fiber.
