As a result,an analogue waveguide configuration of metal-transparent film-absorption substrate,which can accommodate a series of resonant modes,is formed due to a bigger reflectivity on the absorption substrate for the small angle of incidence.

A core-cladding waveguide structure of lithium niobate single crystal fiber is achieved by using MgF_2 firstly as a diffusion source for Mg-ion indiffusion.

Aiming at the high-power laser,the vertical far-field divergence angle was reduced by the very narrow waveguide and the mode expanding waveguide structures,a simplified model of the far-field distribution of quantum-well lasers with a very narrow waveguide structure and the theoretical value of the vertical divergence angle were achieved,the vertical divergence angle was reduced to 2.

Efficient numerical analysis of guided wave structures by compact FDFD with PVL method;

Based on manufacture,performance test and analy- sis of different optical fiber waveguides,the relationships between waveguide and loss,MFD,bend loss,waveguide disper- sion are deduced respectively.

Waveguide is the basic component of integrated optics,and it also plays an important roll in the manufacture of optical devices.

A hybrid method,which combines the line method with the method of equivalent transmission lines, for calculating the dispersion of planar waveguide structures is presented.
