Abstract :
Results of the study a thin near-field structure of the semiconductor laser emission using nearfield optical microscopy (SNOM) are presented. Significant enhancement of resolution is achieved by deconvolution of measured 2-D images using Tikhonov´s method. It made possible to detect the true nano-scale structure of inhomogeneities of a semiconductor laser emission.
