High extinction ratio D-shaped fiber polarizers coated by a double graphene/PMMA stack

Abstract: Abstract:We demonstrate theoretically and experimentally a high extinction ratio and compact size TE-pass polarizer made by a D-shaped fiber coated with a double graphene/PMMA stack. The light propagating in the core of the fiber can be efficiently coupled into the graphene sheet thanks to the giant enhancement of the modal evanescent field associated with the high refractive index graphene/PMMA cladding. The strong interaction between the light and graphene produces a large attenuation difference between mode… Show more

“…After their work, a lot of papers were published reporting the utilization of graphene or graphene oxide in waveguide- or fiber-based polarizers 34–41 . To enhance the extinction ratio (ER) in some of these polarizers, graphene was used in conjunction with metal 38 or dielectric coatings 34,36,39 . However, these efforts did not satisfy the demand for in-line polarizers, mostly due to their high insertion loss (IL) and low ER.…”

“…The functionality of the optical polarizer is to allow one polarization to pass (TE or TM) and the other to be eliminated. In recent years, researchers have implemented many types of optical polarizers, including prism polarizer, sheet polarizer, optical fiber polarizer and optical waveguide polarizer [ 3 , 4 , 9 , 10 ]. Compared with other types of polarizers, optical waveguide polarizer is flexible and easy to integrate with other optical components on one circuit.…”

“…Graphene interacts with light mainly through optical absorption. When graphene is integrated into D-fibers, the absorption can be designed to be highly dependent on the polarization, potentially resulting in broadband, large polarization extinction ratio polarizers [11]- [14]. Additionally, the absorption can be varied electrically to develop optical switches and modulators [8] and lasers with electrically controlled operation regime (continuous wave, Q-switching, or mode-locking) [10], or it can be controlled optically, to produce all-optical switches [9], [15] and saturable absorbers [10], [11], [16]- [20].…”
