Abstract

Systems and methods are provided for providing wideband diffraction limited performance in an optical receiver. A first lens is constructed from a first material and has a first surface and a second surface. A second lens is constructed from a second material and having a first surface and a second surface. The second lens is positioned such that a first surface of the second lens faces a second surface of the first lens across a gap of air. A diffraction grating is applied to one of the first and second surfaces of the first and second lenses.
