对称非线性包层平板波导TE0模的“平台形”场分布
‘Platform-like' Field Distribution of TE0 Mode in a Symmetric Planar Waveguide with Two Identical Nonlinear Claddings
摘要
Abstract
The characteristics of TE0 modes in a waveguide with two identical Kerr type nonlinear claddings and a linear uniform core are analyzed. Both theoretical analysis and numerical examples give the same results. For the focusing case,with increasing modal refractive index, the maximum value of core field gradually decreases. At a definite optical power, when the modal refractive index at the core-cladding interface is equal to refractive index of core, the core field becomes uniformly 'platform-like', while the cladding field rapidly reduces. As the modal refractive index continually increases, the maximum field enters into the two claddings,while the field profile in the core changes to concave. Curves (focusing and defocusing cases) are given for field distributions, relations between modal index and power,ratio of core power to total power versus total power, relations between 'platform'height and core index, relations between 'platform' and core width, and so on.关键词
