IM-1064-10G is used for optical signal intensity modulation and laser pulse shaping. This device is composed of a high polarization extinction ratio (PER) polarizer, an integrated push-pull electro-optic Mach-Zander interferometer and an integrated electro-optical DC bias controller, suitable in pulse-laser and high-power laser systems. Based on Lithium Niobate (LiNbO3) material, IM-1064-10G is fabricated with optical waveguides using High Temperature Proton Exchange (HTPE) and the velocity-matched electrodes for high-frequency region. The IM-1064-10G is highly reliable in performance with on-off extinction ratio (ER) exceeding 22dB. It operates in wide temperature range with extended life time in comparison with other competing technologies such as InP and silicon photonics.
