title: Spatially-resolved self-heterodyne spectroscopy of lateral modes of broad-area laser diodes.
abstract: We investigate the fine structure of the optical spectrum of a broad-area laser diode with approximately 30-MHz resolution using spatially-resolved self-heterodyning technique. We show that this method is capable of measuring the relative powers and spacings of the individual lateral modes.
