研制了一种反射型马赫-曾德尔LiNbO 3光调制器，该调制器采用双短截线结构，可同时调制前向和后向光波，实现低驱动电压的带内操作光调制。使用光学反射，调制效率加倍。制作的调制器的半波电压为2.9 V，在7 GHz。
A reflection-type Mach-Zehnder LiNbO3 optical modulator with a double-stub structure that can modulate both forward and backward lightwave to achieve low-driving-voltage optical modulation for band-operation is developed. Using optical reflection the modulation efficiency is doubled. The halfwave-voltage of the fabricated modulator was 2.9 V at 7 GHz.
