目前流行的光波导理论是建立在麦克斯韦方程基础上的宏观理论。虽然在解决一些波导技术问题方面宏观理论已取得了很大成功,但对一些较基本的问题宏观理论却无能为力。例如光是怎样通过与波导物质相互作用而在波导中传播的,为什么波导导模光的性质与一般光的性质大不相同(如导模光可集中在很小的区域中传播而几乎没有衍射损耗)等等。搞 The prevailing optical waveguide theory is a macroscopic theory based on Maxwell’s equations. Although macroeconomic theory has achieved great success in solving some waveguide technology problems, it can not do some macroeconomic theories on some basic problems. For example, how light travels in a waveguide by interacting with the waveguide material, the properties of the waveguide mode light are quite different from the properties of a normal light (eg, guided light can be concentrated in a small area and propagate with little diffraction Loss) and so on.
