PM-1550-10G is used for optical signal phase modulation and spectral broadening. This device is composed of a high polarization extinction ratio polarizer and an electro-optic phase modulator suitable for short and long-haul telecommunication applications. Based on Lithium Niobate (LiNbO3) material, PM-1550-10G is fabricated with waveguides using High Temperature Proton Exchange (HTPE), and group-velocity matched electrodes operating at high frequency band. The PM-1550-10G provides highly reliable performance over wide temperature range and with extended life time in comparison with other competing technologies such as InP and silicon photonics.
