An optical communications system comprising:
- a focal element configured to transmit a signal;
- an aperture lens configured to focus the signal onto said focal element, said aperture lens comprising a surface;
- and
- a phase change layer positioned on at least a portion of said surface of said aperture lens, said phase change layer configured to shift a phase of the signal, producing a positive amplitude from a diffraction pattern from said focal element.

A phase reversal apparatus for an optical communications system including:
- a focal element configured to transmit a signal;
- and
- an aperture lens configured to focus the signal onto said focal element, said aperture lens comprising a surface, said phase reversal apparatus comprising a phase change layer positioned on at least a portion of said surface of said aperture lens, said phase change layer configured to shift a phase of at least a portion of the signal, producing a positive amplitude from a diffraction pattern from said focal element.
A method for optimizing an optical communications system, said method comprising:
- receiving a signal at an aperture lens, said aperture lens comprising a surface;
- transmitting the signal onto a focal element positioned at a focus of the aperture lens;
- and
- shifting a phase of at least a portion of the signal using a phase change layer positioned on at least a portion of said surface of said aperture lens, producing a positive amplitude from a diffraction pattern from said focal element.
