Lithium niobate electro-optical phase modulator(lithium niobate modulator) yakavakirwa patitanium diffusion process ine hunhu hwekurasika kwekuisa pasi, high modulation bandwidth, low half wave voltage, high damage optical power, etc. Inonyanya kushandiswa muminda ye optical chirp control in high-speed optical communication systems, phase shift in coherent communication systems, chizvarwa chesidebands muROF systems, uye kuderedzwa kweBrillouin scattering (SBS) inokurudzirwa mune analog optical fiber communication systems.
