Abstract

A 5Gbps LiNb $O_3$ optical phase modulator was packaged and described. A APE(annealed proton exchange) method was employed for the optical waveguide and the electrode of ACPS (asymmetric coplanar strip) type was formed by electro-plating on LiNb $O_3$ fort applying microwave signal. The resulted phase modulator exhibited a single mode at a 1550nm wavelength and Its modulation bandwidth, Insertion loss and driving voltage showed 7$^{GHz}$, 3. $O^{dB}$ and 6V. respectively.y.
