| Outline of Final Research Achievements |
The realization of silicon-based lasers will be important for the energy-saving human lives. In this project, the lasing mechanism for high-Q nanocavity-based Raman silicon laser was studied using the well-developed nano-fabrication technique and microscopic spectroscopy. We found that the dynamical resonance wavelength shift cause a detrimental effect for the laser performances. In addition, we developed a novel technique to investigate the excitation-wavelength dependence of the optical gain. We also measured the frequency difference, operating wavelength dependence, and temperature dependence. Based on these findings, structural improvement was added and as a result, the production yield and output power was increased.
