N2 - Transmitted light measurements in ultraviolet and visible light regions have revealed giant optical anisotropy at 298K in the high-Tc superconducting cuprates Bi2Sr2CaCu2O8+δ crystals with optimal doping. We employed a generalizedhigh- accuracy universal polarimeter to measure linear birefringence and linear dichroism in ultrathin (001) single crystals of Bi2Sr2CaCu2O8+δ. In particular, remarkable anomalies in linear birefringence and linear dichroism were observed at 345 and 330 nm, respectively. These results explicitly suggest that the large optical anisotropy should be carefully considered when discussing the symmetry breaking of this compound, based on the experimental results of optical measurements.
