1550nm Electro-optic Intensity Modulator
The LiNbO3 electro-optic intensity modulator based on the M-Z push-pull structure has low half wave voltage and stable physical and chemical properties, and the device has a high response rate. The KT-AM-15 series is a simulated electro-optic intensity modulator designed for the 1550nm wavelength band, with a 2.5G 10G 20G 40G rate option. It is widely used in high-speed optical communication systems, Q-switching systems, laser mode-locking, and fiber sensing fields.
