In this paper we created ultra-narrowband wavelength selective emitter with Q-factor exceeding 180. The devices are designed by Bayesian optimization. The mechanisms of radiative transfer emission are clarified by using Rigorous Coupled-Wave Analysis. The optimized structure consists of aperiodic multiple layers of alternating materials with varying refractive index. The obtained structure was fabricated by sputtering and measured by fourier transform infrared spectroscopy. As a result, we demonstrated high and sharp emissivity in the infrared region.
