Glass has long been established as the lowest loss and most manufacturable optical material. However, the low third-order nonlinearity of silica glasses and the absence of a second-order nonlinearity, forbidden by the inherent macroscopic inversion symmetry of amorphous materials, have resulted in many material investigations searching for a suitable complimentary nonlinear optical material. To date, no material has been found that combines a strong nonlinearity with the unrivaled optical transparency, manufacturing flexibility, enviromental stability, and opto-electronic and microelectronic integrability of glass. |
