PROBLEM TO BE SOLVED: To provide a compact carbon nanotube Raman light source not requiring an expensive optical crystal or optical component, or an advanced semiconductor crystal growth technique, and to provide a silicon photonic crystal resonator for use therein.SOLUTION: In a silicon photonic crystal resonator 1 of high Q value in which semiconductor carbon nanotubes are arranged as an optical gain medium, the wavelength of Raman light outputted by converting the exciting light into the long wavelength side by an amount of Stokes shift due to Raman scattering process is set in a wavelength region where the optical absorption loss by the semiconductor carbon nanotubes is less, and the resonance wavelength of the silicon photonic crystal resonator 1 is set to the wavelength of the Raman light. |
