Abstract
The present disclosure relates to a thermally modulated optical lens apparatus that includes an electrically resistive element that has patterned features. The patterned features may be micro-sized or smaller and may create an electrical resistance density across the electrically resistive element. The electrically resistive element is capable of electrically connecting to a controllable electrical source. The apparatus also includes at least one thermo-optical material in thermal contact with the patterned features of the electrically resistive element. The at least one thermo-optical material can have an optical refractive index profile that corresponds to the electrical resistance density.
