title: Ultrathin polarizing films for the near-infrared region consisting of stacked anisotropic gold island films.
abstract: We have fabricated an ultrathin polarizing film for the near-infrared region by stretching a periodic multilayer consisting of gold island layers and glass layers. A polarizing film with an extinction ratio of 21.5 dB and a thickness of ~0.2 microm has been realized at the wavelength of 1300 nm by use of a periodic multilayer of 12 gold island layers with a mass thickness of 21 nm. This polarizing film could be useful as a micropolarizer for fiber-embedded in-line optical devices and hybrid integrated optics.
