The optical properties of YBa2Cu3O7-δ are studied by electroreflectance spctra. In the visiblr range, two peaks at 1.78 eV and 2.43 eV are obtained. Analysis of the features show the utility of the modulated reflectance techniques for studying the band structure of superconducting system. Hence a new means to study the optical properties of superconducting system is suggested.
