Abstract
We present numerical simulations, based on elementary mode method, of field emitted by broad-area laser diodes. The near field is expressed as a superposition of modes with sinusoidal spatial amplitude inside the laser resonator and zero outside. The assumed functional form of the modes is used to find the intensity distribution in the far-zone. This information is then used to construct the elementary-mode decomposition in the near-field. The validity of the elementary-mode approach was verified by comparing the intensity and the degree of coherence at various distances from the source.
