    Experimental data demonstrating the waveguiding properties of a layer composed of Si nanocrystals embedded in a silica slab are presented. It was demonstrated that the room temperature guided emission in the red spectral region, originating from the luminescent nanocrystals contained polarization distinguished transverse electric (TE) and transverse magnetic (TM) peaks, the structure of which was a sensitive function of observation angle. The investigation of optical gain in a sample implanted to a dose of 4 × 1017 cm-2 was reported.
