The optical conductivity of optimized doped YBa2Cu3O7-delta (delta = 0.0, T
-c= 92 K) superconductors, which are frequency dependent, has been theoreti
cally investigated based on two-component (Drudel and mid infrared terms) a
pproach within the Fermi liquid description. Our approach incorporates the
Drude contribution as well as hopping:of charge:carriers in the model: diel
ectric function-along with the structure factor. It,explains the anomalies
observed-in the optical measurements-for the normal state::as the frequency
dependence of optical conductivity using the Drude term which gives a shar
p peak at zero,frequency, and a long tail at higher frequencies, i.e. in th
e infrared region. The extra term (hopping carriers) gives a peak value in
the optical conductivity Centred in the mid infrared region. The two specie
s of charge carriers contribution to the conduction in the CuO chain layer
as well as CuO layer as well as CuO2 account for the-optical conductivity i
n the mid infrared:as well as infrared frequency regions. The analysis reve
als an interesting relation sigma(CuO2) layer approximate to 3 sigma (chain
layer), and the nature for optical conduction with energy is similar quali
tatively, the only difference is quantitatively. It is shown that the analy
sis is consistent with the published data on optical conductivity in optimi
zed-doped YBa2Cu3O7-delta superconductors.
