IM-1310-10G is used for optical signal intensity modulation and pulse shaping. The device is composed of a high polarization extinction ratio polarizer, an integrated push-pull electro-optic Mach-Zander interferometer and an integrated electro-optical DC bias controller.  Based on Lithium Niobate (LiNbO3) material, IM-1310-10G is fabricated with optical waveguides using High Temperature Proton Exchange (HTPE) process and the group-velocity matched electrodes for high-frequency region. The IM-1310-10G features on-off extinction ratio (ER) exceeding 25 dB with low-drive voltage of 6 Volts at 10 GHz. The device is highly reliable in performance, operates over very wide temperature range and has extended file time in comparison with competing technologies such as InP and silicon photonics.
