Abstract
A microlens has a material composition gradient that varies along the z-axis of the microlens to provide desired refractive properties in conjunction with the surface shape of the microlens. A method for designing the microlens may include defining a microlens surface shape, defining desired refraction properties of the microlens, and determining a refractive index gradient of the microlens in the direction of the z-axis using the desired refraction properties and the defined surface shape of the microlens. A method for fabricating the microlens may include depositing a material having a material composition gradient that is determined based on a lens shape and desired refractive parameters, and forming the microlens having the desired surface shape in the material.
