Paper Abstract

A Wide-Band LiNbO3 Electro-Optical Modulator was designed and Fabricated. The LiNbO3 integrated optical intensity modulators consist of Mach-Zehnder interferometer optical waveguide circle and coplanar waveguide (CPW) modulation electrode structure. The effects of CPW’s parameter on the transmission performance of microwave by using the finite element method. Experimental results show that the fabricated Modulator obtain insert loss of 3.5dB, the extinction ratio of 30dB, the half-wave voltage of the DC electrode of 4V,the half-wave voltage of the traveling-wave electrode of 5.5V, the power reflection of less than -13dB, the 3dB bandwidth of 18GHz
