Narrow Luminescence Linewidth of a Silicon Quantum Dot
Physical Review Letters, 2005 Single-dot luminescence spectroscopy was used to study the emission linewidth of individual silicon nanocrystals from low temperatures up to room temperature. The results show a continuous line narrowing towards lower temperatures with a linewidth as sharp as 2 meV at 35 K.

Narrow-linewidth fiber laser operating at 155 μm [PDF]
Optics Letters, 1987 We report the fabrication and operation of an Er(3+)-doped silica single-mode fiber laser operating at 1.55 microm and using a distributed fiber grating to provide feedback. The output bandwidth was measured as 0.04 nm, significantly narrower than the conventional cavity design. The laser had a threshold of 13 mW and a slope efficiency of 5%.
