摘要:
In a color-center light source, a color center is formed artificially. A predetermined single atom is removed from the surface of a defect-free ionic crystal so as to form a lattice defect. Optical transition of the defect is utilized so that it functions as a light source.

A fiber coupling device comprises fixing parts 1V, to which the respective ends of two optical fibers 5 and 6 are fixed, photonic crystal 2, disposed inside the light path of light that propagates across the abovementioned ends, and external force application means 3, which applies an external force to photonic crystal 2. When an external force is applied by external force application means 3 to photonic crystal 2 while light is being propagated inside one optical fiber 5, the photonic band gap of photonic crystal 2 changes and light of a wavelength that is in accordance with this photonic band gap is output from the other optical fiber 5.
