We have investigated the spectral reflectance of thin YBa2Cu3O7−δ films deposited on twin-free NdGaO3(001) substrates. Using polarized light in the spectral range between 50 meV and 6 eV, we found a significant a-b anisotropy near the plasma edge. On the basis of a Lorentz–Drude model we have calculated the tensor components of the dielectric function parallel to the a and to the b axis, respectively. The obtained results are compared with the a-b anisotropy of single domain crystals.
