We　demonstrate　a　multi-focal-plane　see-through　near-eye　display　with　effective　focus　cues　enabled　by　wavelength　multiplexing.　A　spectral　notch　filter　is　implemented　as　the　wavelength-sensitive　depth　separation　element.　The　vergence-accommodation　conflict　can　be　mitigated　with　the　proposed　design　without　space-　or　time-multiplexing.　Another　design　of　a　dual-focus　projection　module　for　the　waveguide-type　augmented　reality　devices　using　wavelength-multiplexing　is　also　presented.　(C)　2019　Optical　Society　of　America　under　the　terms　of　the　OSA　Open　Access　Publishing　Agreement
