Outline of Final Research Achievements |
In this project, we investigated new concepts and techniques to realize arbitrary control of thermal emission, such as the conversion from a broadband to a narrowband thermal emission spectrum with minimal loss of energy at a desired wavelength and high-speed control of thermal emission. We have successfully demonstrated the following: (1) the development of mid-infrared ultra-narrowband thermal emitters whose linewidths are less than 1/100 of that of a blackbody emitter, (2) the realization of ultra-fast electrical control of thermal emission (~MHz), (3) the development of near-infrared narrowband thermal emitters operating above 1000℃, (4) the discovery of a scheme of narrowband thermal radiation transfer exceeding the blackbody limit via near-field coupling of an emitter and an intermediate transparent substrate attached to the top of an absorber.
