Abstract :
Summary form only given. Progress in establishing a large second-order nonlinearity in silica fibers is reviewed. A second order nonlinearity has been induced in germanosilicate fibers by poling the fiber with a large applied electric field and either an elevated temperature [100 - 200 C] or UV irradiation [193 nm or 248 nm]. Nonlinearities approaching that of LiNbO3 have been reported. Once the nonlinearity is established, the field can be removed leaving a permanent effect.
