  • Abstract
    For highly efficient operation, a new type LiNbO3 Mach-Zehnder intensity modulator using electrodes buried in the buffer layer was designed and fabricated. The modulator was designed considering velocity matching between light and microwave, microwave propagation loss and characteristic impedance Z0 of 50 Omega . This modulator for a 1.5 mu m wavelength operates with a Vpi of 3.2 V, a 3 dB down bandwidth of 14 GHz and a temperature dependence of 17 mV/ degrees C.
