Based on the mode-coupled theory,a new guided-wave optic cell written by UV light is discussed.

In this paper,we present the TM mode dispersion equations of symmetrical and unsymmetrical multi-layer planar optical waveguide based on the Analytic Transfer Matrix Method(ATMM),which can exactly determine the mode characteristics of planar optical waveguide.

Propagation characteristics of the planar waveguide with chiral core;

When the ESI model a n d the original waveguide have the best approximated field distribution, the prop agation quality of planar waveguide efficiently can be predicted based on ESI mo del in specific range.

Coupling losses in different planar waveguide resonators are calculated for anarbitrary waveguide mode.

Investigation on guided mode characteristics of a uniaxially anisotropic left-handed material slab waveguide;

The propagating characteristics of a symmetrical three-layer slab waveguide with mu-negative (MNG) media are studied in detail.

Taking the symmetric slab waveguide as an example,we show that radiation modes of a weakly guiding planar optical waveguide can be approximated by the free space modes,their field expression and normalization constants are simple and understandable physically and can be obtained directly without any calculation.
