Erasure of second order nonlinearity in thermally poled fused silica by electron implantation

Abstract

We show that implantation of electrons erases the second-order nonlinearity in thermally poled silica. This technique provides a versatile new means of realizing quasi-phase-matching structures for parametric frequency conversion in glass optical fibers and planar waveguides.
