Phase modulator

This product is a lithium niobate high-speed phase modulator with independent property rights, and the crystal preparation and coupling packaging are all localized. Features high bandwidth and low half-wave voltage.
This product is made of waveguide by titanium diffusion or proton exchange process. The optical fiber and waveguide are tightly coupled to achieve low back reflection. Among them, the insertion loss of the device is <3dB, the half-wave voltage is <3.5V, and the bandwidth is up to 10GHz
