| Outline of Final Research Achievements |
Circularly polarized light source based on a complex system of semiconductor three-dimensional chiral photonic crystals and quantum dots was realized by use of circularly polarized photonic band structures. This achievement results from manipulating the density of states in the vacuum field for one of the circular polarizations. The emission intensity difference as well as the radiative lifetime difference between the two circular polarizations confirmed the operating principle of the obtained circularly polarized light source. In addition, a chiral cavity mode for circularly polarized light was also demonstrated. These achievements through this research project can be applied to information technology, chemistry, or biology as robust circularly polarized light sources formed by geometrical structures with chirality.
