Abstract
In access to optical spectroscopy of heavily underdoped detwinned YBa2Cu3Oy (YBCO) crystals, we re-examine the doping dependent evolution of infrared spectra in the CuO2 plane of underdoped YBCO in terms of two-component optical conductivity. The extended Drude model analysis is applied to the two-component conductivity, and the results are compared with experimental data in the pseudogap state. We demonstrate that a model consisting of a Drude and Lorentz oscillator components reproduces characteristics of infrared spectra in underdoped YBCO.
