Propagation Characteristic Of LNN Nonlinear Planar Optical Waveguide

Nowadays, in information optics and integrated optics, various nonlinear optical devices have been manufactured, not only for the features of small dimension, light, low loss, but also for the characteristics of strong nonlinear effects and fast response. Thus it is important to study and master the propagation characteristics of nonlinear optical waveguides for research, experimental measurement and manufacture of nonlinear integrated optics devices.By application of the transfer matrix method, propagation characteristic of beam in nonlinear Kerr-type planar optical waveguide was analyzed and studied .The main contributions are as follows.1. Reviewing the published paper on the propagation characteristics of dielectric waveguides and the theory of nonlinear waveguides, considering the current situation in domestic and international researches on theory and applications, establish the theme and topic of this paper.2. By application of the transfer matrix method, propagation characteristic of TE and TM beam in nonlinear Kerr-type planar optical waveguide is analyzed; mode eigenvalue equation of TE, electric fields distributions are obtained from the accurate solution to the mode eigenvalue equation.3. There are two electric vectors in TM mode, so it is complex to study the propagation characteristic of TM, by adopting new method, magnetic fields is firstly calculated, then from the relations between electric fields and magnetic fields, electric fields distributions of TM are obtained.4. The propagation characteristic of TE and TM is compared and analyzed; Relation curves of optical power on effective index are obtained from the accurate solution to the mode eigenvalue equation.5. The relation between electric fields and nonlinear coefficient is studied. Relation curves of electric fields on nonlinear coefficient and effective index on depth of core are obtained from the accurate solution to the mode eigenvalue equation.
