提出了一种中微子对的量子电动力学（QED）无背景辐射发射（RENP）方案，以实现迄今为止无法实现的中微子性质的精确测定。背景抑制的要点是，波矢量沿着波导中（以及光子晶体型光纤中）的传播方向与频率之间的色散关系由离散化的非零有效质量修改。这个有效质量作为允许频率的截止，并且可以通过选择大于中微子质量的截止来选择没有所有宏观相干放大QED过程的RENP光子能量区域。
A scheme of quantum electrodynamic (QED) background-free radiative emission of a neutrino pair (RENP) is proposed in order to achieve precision determination of neutrino properties so far not accessible. The important point for the background rejection is the fact that the dispersion relation between the wave vector along the propagating direction in the wave guide (and in a photonic-crystal-type fiber) and the frequency is modified by a discretized non-vanishing effective mass. This effective mass acts as a cutoff of allowed frequencies, and one may select the RENP photon energy region free of all macro-coherently amplified QED processes by choosing the cutoff larger than the mass of neutrinos.
