Abstract

Polarized infrared reflectance measurements are reported for crystals of La_2−xSr_xCuO_4−δ and YBa₂Cu₃O_7−δ. Free-carrier reflectance is observed in the copper oxide planes, and strong phonons are observed in the perpendicular direction. The interpretation of the infrared optical properties is discussed.
