Thermal poling of silica optical fibers using novel liquid electrodes

Thermal poling of silica optical fibers using novel liquid electrodes
Thermal poling is a well-known technique for inducing second-order nonlinearities in centrosymmetric silica optical fibers. However, some 25 years since its discovery, there still remain a number of issues that prevent the realization of very long length, highly efficient all-fiber nonlinear device applications that includes frequency conversion or sources of polarization-entangled photon pairs. In this paper we report a thermal poling method that utilizes a novel range of liquid metal and aqueous electrodes embedded into the optical fibers. We demonstrate that it is possible to pole samples that are potentially meters in length, characterized by very low losses for efficient SHG processes. The maximum estimated effective value of chi(2) (0.12 pm/V) obtained using Mercury electrodes is the highest reported in periodically poled silica fibers.

Abstract

Thermal poling is a well-known technique for inducing second-order nonlinearities in centrosymmetric silica optical fibers. However, some 25 years since its discovery, there still remain a number of issues that prevent the realization of very long length, highly efficient all-fiber nonlinear device applications that includes frequency conversion or sources of polarization-entangled photon pairs. In this paper we report a thermal poling method that utilizes a novel range of liquid metal and aqueous electrodes embedded into the optical fibers. We demonstrate that it is possible to pole samples that are potentially meters in length, characterized by very low losses for efficient SHG processes. The maximum estimated effective value of chi(2) (0.12 pm/V) obtained using Mercury electrodes is the highest reported in periodically poled silica fibers.
