摘要：

Radial Bragg distributed-feedback (DFB) lasers are designed and studied using the transfer matrix method, allowing an accurate analysis beyond the coupled-mode equations approach (small perturbations). Compared with conventional circular grating DFB lasers, incorporating periodic gratings, lower threshold levels, and enhanced mode discrimination are achieved by employing an optimal design strategy for the radial Bragg reflector.
