Paper Abstract

Based on the off-axis theory, by using the angular spectrum representation, the Fourier transform and the inverse Fourier transform, an inverse source model of a laser diode has been obtained. An accurate non-paraxial inverse source formulation is proposed by which the inverse source problem can be solved rigorously with the far-field measured data. So the accurate analytical solution to the source distribution can be obtained with the far-field intensity distribution, and then the parameters relating to the waveguide structure can be obtained.
