Development of elliptical nanostructured gradient index microlens

In this paper, we demonstrate the feasibility of using the nanostructured micro-optics technology to create a large diameter quantized elliptical microlens. Nanostructured gradient index elements have discrete internal structure with feature sizes much smaller than the wavelength of the incident light. The nanostructured lens is composed of two silicate glasses with various refractive indexes. Large diameter elliptical microlens is developed. Optical performance of microlens is verified numerically. Effective focal lengths of 220 and 116 for are predicted for wavelength of 1300 nm.
