摘要：

An efficient full-wave analysis technique for one-dimensional optical domains, known as the Recursive Green's Function Method (RGFM), is presented for evaluation of distributed feedback (DFB) laser cavities with arbitrary material profiles, The method first constructs the Green's function of an inhomogeneous domain and subsequently uses Green's theorem to determine the laser optical field, lasing wavelength, and threshold gain. The technique is applied to investigate the performance of three DFB laser structures: a chirped-grating configuration, a modulated stripe width design, and a reduced duty cycle complex-coupled device, These structures are evaluated in terms of their single-mode lasing behavior and the uniformity of the optical field within the cavity.
