Abstract

Blackbody radiation is modified to enhance the blue spectrum with photonic boxes of ∼200 nm. The modified blackbody radiation has two temperature-independent features. First, the enhanced blue light has the peak intensity pinched at 390 nm with an enhancement factor of over 5000. This peak wavelength corresponds to the resonance wavelength of the largest-number boxes. Second, the spectral width is 90 nm and is governed by the variation of the box size. The physics can be easily explained by the significantly enhanced density of states at a certain spectrum as a result of photonic boxes.
