半波电压低达5.3伏的钛扩散LiNbO_3波导干涉型调制器已研制成功。在6328(?)的光波长下测试,其消光比为97.6％,器件电容为9pF,2dB带宽为700MHz。加300kHz正弦波信号后,测试了器件在不同偏置电压下的响应。
A titanium diffused LiNbO_3 waveguide interferometric modulator with half-wave voltage as low as 5.3 volts has been developed. At an optical wavelength of 6328 (?), The extinction ratio was 97.6%, the device capacitance was 9pF and the 2dB bandwidth was 700MHz. After adding 300kHz sine wave signal, tested the response of the device under different bias voltage.
