Abstract (in Japanese) (See Japanese page) 
(in English) The purpose of this article is to propose a technique for calculating eigenmodes of optical waveguides, in which the complex-envelope formulation is applied to the compact finite-difference time-domain (FDTD) method. We first formulate the envelope compact (EC) FDTD method for the eigenmode analysis. The frequency component can be incorporated into the field equations as a known quantity with the envelope formulation. We next analyze the eigenmodes of a two-dimensional slab waveguide using the EC-FDTD method. It is found that the calculated value automatically converges to the eigenmode and the propagation constant without an exact initial guess of the propagation constant. It is also shown that the results agree well with those of the exact solution.
