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, The generation of sideband of ROF system and the reduction of stimulated Radiation Scattering (SBS) in analog optical fiber communication systems and so on.
Features:
- High modulation bandwidth
- Low half-wave voltage
- High damage optical power
- Low insertion loss
Applications:
- Optical fiber sensing coherent
- Optical fiber communication laser coherent synthesis
- Phase delay( phase shifter )
- Quantum communication
- ROF system
