Popis: A holographic Fresnel lens for coarse wavelength-division-multiplexing (WDM) application in 1300 nm band is described. Letter paper focuses on minimizing the third-order aberrations for off-axis operation of the lens in order to reduce channel spacing and insertion loss. Improved characteristics have been obtained for the lens fabricated according to the theoretical design.
