Abstract The polarized reflectance of thea-b plane of single-domain Bi2Sr2CaCu2O8 crystals is anisotropic above and belowT c . The normal-state infrared conductivity is higher forE‖a whereas the high-frequency conductivity is higher alongb, particularly for transitions associated with the Bi−O layers. BelowT c there is a definite anisotropy to the far-infrared absorption, with a finite absorption forE‖b down to ≈20 meV. This anisotropy of thea-b plane could be due either to anisotropy of the superconducting gap or to anisotropy of the midinfrared component to the conductivity.
