Abstract


The rapid development of the Internet age to promote the rapid progress of communication technology , dense wavelength division multiplexing (DWDM) technology to solve the problem of large capacity of optical fiber communications backbone . Modern optical communication toward a higher capacity , higher speed direction . Integrated optics to modular optical communication devices , miniaturization , large-scale integrated optical circuit is one of the direction of future development of optical communications . In recent years , optical microring important structure of the large-scale integration of optical path has become a focus of attention . It is functional , compact , and has great potential for development . The flexible structure of polymer materials , low prices , and soon a material developed in recent years . It has a high thermo-optic coefficient , a low thermal conductivity , the process is simple and convenient to produce a variety of optoelectronic devices in the study . The proposed scheme is the polymer material technology and ion exchange technology combined produced waveguide devices . This thesis elaborated using signal processing methods to establish the model of the micro-ring resonator , and export -based micro- ring structure of the all-pass filter frequency response , and analyze its characteristics , its dispersion compensation characteristics more detailed analysis . Micro - ring structure produced by dispersion compensation , small size, compact structure , suitable for multi -channel simultaneous compensation . Subsequently also analyzed using the structural design of the micro-ring linear modified type MZ modulator, lossless and lossy microring assisted type Mach-Zehnder (MZ) modulator design . Eliminate the the MZ modulator characteristics of second-order and third-order nonlinear lossless and lossy , and draw polycyclic auxiliary general parameters of the design equation , given for the most commonly used structure parsing expression , which greatly facilitated the design . Characteristics of organic polymer material properties and process conditions , to build a prism coupler measurement equipment film parameters . Measurement of the refractive index and thickness of the device can be completed at the same time on the polymeric film , having a certain degree of accuracy , speed, can be applied simultaneously with various commonly used communication band parameter measurements . Finally explore the polymer material process with an ion exchange technology combined with the waveguide device production method, the design of the waveguide structure and process .
