Abstract

We report on optically induced, sub-microsecond optical switching in an elliptical core neodymium doped, two-mode fiber. The improved response time of this switch, which is three orders of magnitude faster than the 400 microsecond(s) metastable lifetime of Nd³⁺, was provided by rapid cross relaxation within neodymium clusters.
