Lithium niobate ( LiNbO3) straight waveguide phase modulator by titanium diffusion or proton exchange waveguide device production process, low insertion loss, low driving voltage, optical fiber and waveguide by using precision inclined coupling can be obtained with low back reflection.
Low insertion loss
Low driving voltage
Optical and chip precision inclined coupling, greatly reduced back to the light reflection
Encapsulation of small size, light weight
Devices for long-term stability
