The influence of compositional variations on the physical properties such as, density, molar volume, molar refraction, optical energy gap, refractive index, optical basicity, oxide ion polarizability, metallization, and third order nonlinear susceptibility with the variation in CuO content was studied theoretically for glasses of compositions xCuO (100-x)TeO2(x = 25, 30, 35, 40, 50) and the physical parameters related to these compositions were analyzed with theoretical predictions. The calculated density increases with increase in CuO content from 5.850 g cm-3 to 6.030 g cm-3. The theoretical optical energy gap, refractive index, the electronic oxide ion polarizability, the optical basicity and the optical band gap of the glasses were calculated. The glasses were found to possess a high refractive index (2.314-2.433), a comparatively narrow band gap (3.330 eV-2.870 eV), high oxide ion polarizability (2.485 Å3-2.630Å3) and high optical basicity (0.998-1.033). It was found that the values of the third-order nonlinear optical susceptibility are in the range (1.445-2.353) x 10-12 esu.
