摘要
By use of finite-difference time-domain (FDTD) method,an eigenmode analysis in a multiwaveguide structure is presented.Because of difference in propagation constants of different modes,coupling effect is discussed for three and five waveguide systems.The field distribution in multiwaveguides is given.
