在我们对染料渗透蛋白石光子晶体的研究中，我们发现了一种受激发射机制，其特征在于高效、定向的类激光发射和复杂的精细结构光谱。这种机制可以被解释为发生在光子晶体阻带之外的光谱范围内的多模无镜激光振荡的开始。这种现象可能是由于蛋白石的激发区域内的多次后向散射引起的不寻常的光反馈。(C)1999 Elsevier Science B.V.保留所有权利。
In our studies of dye-infiltrated opal photonic crystals, we find a stimulated emission regime, which is characterized by highly efficient, directional laser-like emission and a complex finely structured spectrum. This regime can be interpreted as an onset of multimode, mirrorless laser oscillations that occur in the spectral range outside the photonic crystal stop bands. Such a phenomenon may be due to unusual optical feedback induced by multiple backscattering inside the excited region of the opals. (C) 1999 Elsevier Science B.V. All rights reserved.
