  • Abstract This thesis mainly focuses on producing double-cladding crystal fiber, made of lithium niobate (LiNbO3) and tellurium dioxide crystals by using Laser-Heated Pedestal Growth (LHPG), and being applied to the phase modulator and acoustic detector. First, we use CO2 LHPG to make fibers, the outercladding is SiO2 glass, the indium layer is electrode made of In2O3-SnO, the Indium Tin Oxide (ITO), while the inner core is single-crystal lithium niobate (LiNbO3) with embedded electrodes fiber, and use it as a new electro-optical modulator.
    The core of single-crystal lithium niobate fiber is 5μm, and the ITO electrodes gap is 50μm. The within element half-wave voltage is 6.6 V (Vπ) while the effective electro-optic coefficient is 23 pm/V and the transmission loss of 0.89dB.
    Meanwhile, we use this E-O modulators element applies to the phase adjustment of the fiber-optic gyroscopes and high-speed phase optical switch. In addition, this technique can be applied to the manufacture of other ITO electrodes embedded with single crystal fiber core, and makes it possible to develop a number of electrical regulation fibers with unique properties.
