在磁场中非均匀超导体的 Bogolubov-de Gennes 方法的框架内研究了超导体中偏振光的吸收。详细分析了超导体中产生偏振相关吸收（即二色性）的几种机制。研究了超导体中非偏振光吸收和普通导体中偏振光吸收的关系，并发现了这些情况中未知的几种效应。这些效应是由手性对称性破缺（产生二色性）与超导相干性的相互作用产生的。针对简单模型超导体，对二色性的一个潜在来源，即自旋轨道耦合进行了数值研究。 S0163-1829 98 01122-9
The absorption of polarized light in superconductors is studied within the framework of the Bogolubov‐de Gennes approach to inhomogeneous superconductors in magnetic fields. Several mechanisms which give rise to a polarization-dependent absorption i.e., dichroism in superconductors are analyzed in detail. The relation to the absorption of unpolarized light in superconductors and to the absorption of polarized light in normal conductors is investigated and several effects, not known from either of these cases, are found. These effects arise from the interplay of broken chiral symmetry, which produces dichroism, with the superconducting coherence. One potential source for dichroism, namely spin-orbit coupling, is investigated numerically for a simple model superconductor. S0163-1829 98 01122-9
