Lithium niobate electro-optical phase modulator has the characteristics of low insertion loss, high modulation bandwidth, low half-wave voltage and high damage optical power. It is mainly used for optical chirp control in high-speed optical communication system, phase shift in coherent communication system, ROF The generation of sidebands in the system, and the reduction of stimulated diffuse scattering (SBS) in analog optical fiber communication systems.
Feature:
- Low insertion loss
- High modulation bandwidth
- Low half wave voltage
- High damage light power
Applications:
- Optical fiber sensing
- Optical fiber communication, laser coherent synthesis
- Phase delay (shift)
- Quantum communication
- ROF systems
