In this work, definitions of mode-field radius and divergence half-angle were analyzed according to different kinds of methods. Then, numerical calculation of these definitions was given for the LP01 mode in symmetrical step-index optical fiber. These conclusions may provide a theoretical groundwork for designing optical fiber devices and further researching the propagation characteristic of optical fiber.
