An attempt is made to study the effective electron mass (EEM) in opto electronic materials within the framework of \(\vec{k} \cdot \vec{p}\) formalism in the presence of intense light waves which changes the dispersion relation fundamentally. It is found taking n-type Mercury Cadmium Telluride and Indium Gallium Arsenide Phosphide lattice matched to Indium Phosphide that the EEM exhibits increasing dependency with wavelength as the later one changes from red to violet together with the fact with increasing light intensity the same mass is being enhanced with different numerical values. The variations of EEM with light intensity and wavelength reflect the direct signature of intense light waves on the band structured dependent properties of opto electronic materials. In the absence of external photo excitation all the results get transformed to the well-known expressions as given in the literature and thus confirming the compatibility test.
