Abstract
90° phase matching in periodically poled fused silica is achieved over approximately 2 mm at a wavelength of 1064 nm. Electrical poling was done at 5 kV for 120 min using photolithographed periodic electrodes on fused silica glass at 250 °C. A nonlinearity equivalent to d 11/200 of quartz is estimated from measurements. Several phase‐matched interactions are reported and the implications for device applications discussed.
