III-Nitride-based light-emitting diodes (LEDs) are already commercialized for instance blue and green LEDs. It is very contributed as energy saving light source all over the world. This material is a very attractive material, capable of the emitting range is not only blue light but also UV and visible light. Moreover, application as a power device is also possible, it is one of the materials considered to lead the energy saving society in the future. Visible light LED has a wide range of applications. Visible light LED has a wide range of applications. we expect that there is some application, for instance, μ-LED display, optical communication, plant cultivation, medical treatment, and so on. In the seminar, I will talk about III-Nitride-based visible light emitting devices and introduce recent research with outstanding metalorganic chemical vapor deposition (MOCVD) growth technique.

New nanolasers for quantum information sources

Integrating coherent light sources at the nanoscale with spasers is one of the most promising applications of plasmonics. In a spaser, localized plasmon polaritons (LPPs) waves occurring at the metal-dielectric interface are amplified by an active medium. Under specific conditions, the gain of plasmonic modes can overcome the absorption losses occurring in the metal and stimulated emission of radiation occurs, as experimentally observed in optically pumped spasers. Despite the large body of experimental research, the theoretical understanding of the spaser dynamics is still challenging
