Second-harmonic generation using gratings optically written by mode interference in poled optical fibres

M.E.Fermann, L.Li, M.C.Farries, L.J.Poyntz-Wright, and L.Dong


Second-order nonlinear susceptibility gratings are induced in optical fibers by mode interference of high-intensity blue light in the presence of an external dc electric poling field. An a result, efficient second-harmonic generation can be obtained for any infrared design wavelength.
