Description
The LiNbO3 electro-optical intensity modulator based on the M-Z push-pull structure has a low half-wave voltage and stable physical and chemical characteristics, and the device has a high response rate, and is therefore widely used in high-speed optical communication systems, optical Q-switched systems, laser mode-locking, and fiber sensing.
