An electro‐optic (EO) polarisation conversion type modulator for short‐wavelength light using periodically poled MgO:LiNbO 3 is fabricated and the characteristics are evaluated using a tunable GaN laser. High‐quality domain‐inverted gratings with 3.6 μm were obtained over a 1.0 × 1.0 mm 2 area. The maximum conversion efficiency, as high as 91%, was obtained. The wavelength bandwidth was 0.7 nm, which was in good agreement with the calculated value, and high wavelength selectivity was obtained.
