説明

<jats:p>A magneto-optical switch using a yttrium-iron-garnet crystal plate with phase matching films requiring a drive voltage of only 5V is demonstrated at 1.3 μm wavelength. Using a semihard magnetic material, we developed a bistable magneto-optical switch which drives with a switching speed of 20 μs. An extinction ratio of 24 dB was obtained.</jats:p>
