Diagonal and off-diagonal optical conductivity spectra have been determinedform the measured reflectivity and magneto-optical Kerr effect (MOKE) over abroad range of photon energy in the itinerant ferromagnetic phase ofCuCr$_2$Se$_4$ at various temperatures down to T=10 K. Besides the low-energymetallic contribution and the lower-lying charge transfer transition at$E$$\approx$2 eV, a sharp and distinct optical transition was observed in themid-infrared region around $E$$=$0.5 eV with huge magneto-optical activity.This excitation is attributed to a parity allowed transition through the Se-Crhybridization-induced gap in the majority spin channel. The large off-diagonalconductivity is explained by the high spin polarization in the vicinity of theFermi level and the strong spin-orbit interaction for the related chargecarriers. The results are discussed in connection with band structurecalculations.
