Glasses for non-linear optics
Glasses for non-linear optics
Although glasses have relatively-low non-linear coefficients, the advent of low-loss guided-wave structures such as optical fibres allows this disadvantage to be offset by the use of long interaction lengths and very high optical intensities. Most work to date has concentrated on silica fibres which are readily available but have a particularly low third-order non-linearity, as well as poor electro- and magneto-optic coefficients. Recently, however, it has been discovered that by appropriate doping of silica and operating in the blue region of the spectrum, defects in the glass can be excited which impart photochromic and photorefractive properties. If aligned (poled) by an electric field, the defects also give rise to substantial second-order nonlinearities and allow second-harmonic generation and Pockels effects.

Abstract
Although glasses have relatively-low non-linear coefficients, the advent of low-loss guided-wave structures such as optical fibres allows this disadvantage to be offset by the use of long interaction lengths and very high optical intensities. Most work to date has concentrated on silica fibres which are readily available but have a particularly low third-order non-linearity, as well as poor electro- and magneto-optic coefficients. Recently, however, it has been discovered that by appropriate doping of silica and operating in the blue region of the spectrum, defects in the glass can be excited which impart photochromic and photorefractive properties. If aligned (poled) by an electric field, the defects also give rise to substantial second-order nonlinearities and allow second-harmonic generation and Pockels effects.
