Abstract

We demonstrate a fast, stable, all-optical switch using a thermal effect in cobalt-doped fiber. 46 ns switching is accomplished in a 10-m Sagnac loop containing a 2.55-cm length of doped fiber. Compared to other demonstrated all- optical switches using doped fibers, this switch offers a significant increase in speed and stability, as well as a significant reduction in fiber length.
