Using coherent THz pulse spectroscopy, we have analyzed the electrodynamic properties of thin YBa2Cu3O7-δ films in the temperature range between 10 and 300 K. The temperature dependence of the London penetration depth in c-axis direction determined from the complex conductivity yields clear evidence for d-wave symmetry of the order parameter.
