N2 - We report on the spectral properties of an inhomogeneously-pumped circular-grating distributed-feedback semiconductor laser. Numerically modeling the exact coupled-mode equations, we find that, in comparison with the homogeneous case, a Gaussian optical pump results in greater azimuthal mode discrimination, a broader multi-mode spectral envelope, and a wider fundamental linewidth.
