“…One method of constructing a fiber polarizer is to use an optical fiber with a portion of its cladding removed and replaced with a thin-film overlay. Materials that have been used for this purpose include metal films [2], birefringent crystals [3] and liquid crystals [4]. However, these devices typically have a relatively narrow operation bandwidth, and/or high losses, which limit their application potential.…”

Abstract-Graphene is a two-dimensional material which, as a result of its excellent photonic properties, has been investigated for a wide range of optical applications. In this paper, we propose and fabricate a commercial grade broadband graphenebased fiber polarizer using a low loss side-polished optical fiber platform. A high index polyvinyl butyral layer is used to enhance the light-graphene interaction of the evanescent field of the core guided mode to simultaneously obtain a high extinction ratio ∼37.5 dB with a low device loss ∼1 dB. Characterization of the optical properties reveals that the polarizer retains low transmission losses and high extinction ratios across an extended telecoms band. The results demonstrate that side-polished fibers are a useful platform for leveraging the unique properties of lowdimensional materials in a robust and compact device geometry.

“…SP-based methods have been introduced to demonstrate polarization-selective devices due to the dependence of polarization in coupling between light and SP [16][17][18]. SP could be excited when the electric field is perpendicular to the metal interface (TM wave), but hardly when parallel (TE wave).…”

In this paper, we propose a gear-like metallic core fiber for the generation of a radially polarized mode based on the significant attenuation loss for different transverse modes and a mode reversion mechanism. The mode extinction ratio higher than 40 dB is obtained within 1 cm of such fiber. Our design offers a potential way to obtain a radially polarized beam efficiently.Index Terms-polarization-selective devices, radially polarized beam, fiber design.

“…In 1986, Feth and Chang optimized the performance of the metal-clad fiber polarizer. A very thin metal film is deposited upon the top of the polished fiber substrate [5]. A fiber polarizer was made using an etched D-shaped fiber coated with indium by Dyott et al [6].…”

The transmission losses and lengths of two polarized fundamental modes for a metal-coated eccentric core optical fiber (ECOF) are considered based on the finite-element method. Three typical thin metal films (Au, Ag, and Cu) are used and deposited on the walls of the cladding of ECOF. The variations of the transmission losses and lengths are investigated with different eccentricity, core radii, and metal film species. The numerical results indicate that the optical spectrum of a metal-coated ECOF can be tuned easily by changing the structure parameters of the fiber. The fundamental mode of metal-coated ECOF shows good polarization dependency. It is forecasted that the attenuation difference between the two polarization modes may be used to design an in-fiber polarizer.
