Abstract

A three-dimensional tungsten photonic crystal is thermally excited and shown to emit light at a narrow band, λ = 3.3–4.25 μ m . The emission is experimentally observed to exceed that of the free-space Planck radiation over a wide temperature range, T = 475–850 K . It is proposed that an enhanced density of state associated with the propagating electromagnetic Bloch waves in the photonic crystal is responsible for this experimental finding.
