“…Basically only the TM polarized light (with an electric field perpendicular to the metal surface) can be coupled to the high-loss SPPs mode while the TE polarized light cannot, which makes SPPs ideal for constructing highly compact polarizers. Based on the principle of polarization-dependent excitation, Y. Wakabayashi proposed a TM-pass/TE-stop polarizer consisting of a silver film sandwiched between dielectric gratings and demonstrated an extinction ratio more than 17 dB over a wavelength range of 1500 nm to 1750 nm [9]. Using a side polished fiber coated with a graphene layer, Q. L. Bao proposed a TMstop/TE-pass polarizer with an extinction ratio up to 27 dB in the telecommunications band, based on the fact that only a TE mode surface wave can be supported by the graphene layer [10].…”

Abstract:We propose a novel optical microfiber-loaded plasmonic TE-pass polarizer consisting of an optical microfiber placed on top of a silver substrate and demonstrate its performance both numerically by using the finite element method (FEM) and experimentally. The simulation results show that the loss in the fundamental TE mode is relatively low while at the same time the fundamental TM mode suffers from a large metal dissipation loss induced by excitation of the microfiberloaded surface plasmonic mode. The microfiber was fabricated using the standard microheater brushing-tapering technique. The measured extinction ratio over the range of the C-band wavelengths is greater than 20 dB for the polarizer with a microfiber diameter of 4 µm, which agrees well with the simulation results.

“…Polarization controlling devices such as polarizers, [1][2][3][4] polarization splitters, [5][6][7][8][9][10][11][12][13][14][15] and polarization converters and rotators, [16][17][18][19] are essential elements in coherent optical communication, sensing, signal processing, and other areas where polarization state of light should be taken into consideration. Over the last decades, various structures for polarization controlling devices have been proposed, designed, or fabricated, among which the directional coupler structures (DCs) are perhaps the most popular candidates due to the advantages of simple structure and broad bandwidth.…”

A three-guide directional coupler composed of two slot waveguides and one silicon wire with a function of transverse electric (TE)-pass/ transverse magnetic (TM)-splitting is proposed and designed using a modified 3-D full-vectorial beam propagation method. In our design, quasi-TE modes fed in the middle silicon wire pass through without coupling, whereas quasi-TM modes fed in the same channel are evenly split into the outer slot waveguides. With properly chosen parameters, a TEpass/TM-splitting directional coupler with a length of 22.6 μm, including the straight coupling region and the S-bends, is achieved with the crosstalk of −31 and −35 dB for quasi-TE and quasi-TM modes, respectively. In addition, the tolerances to the structural parameters and operating wavelength are also investigated in detail.

We investigate the mode properties of planar dielectric aluminum-quinoline (Alq3) multilayer waveguides comprising one single or three equally spaced embedded nanometer-thin (∼10 nm thick) Alq3-Mg0.9:Ag0.1 composite metal-island layers. The plasmonic waveguides were fabricated by organic molecular beam deposition. Transverse magnetic (TM) and transverse electric (TE) modes were selectively excited using the m-line method. The symmetric plasmonic TM0 mode was launched in all waveguides and—in addition—two higher order plasmonic TM1 and TM2 modes were generated in waveguides comprising three metal layers. Other TM modes have hybrid dielectric-plasmonic characters, showing an increased effective refractive index when one electric field antinode is close to a metallic layer. TM modes which have all their antinode(s) in the dielectric layers propagate essentially like dielectric modes. TE modes with antinode(s) at the position of the metal layer(s) are strongly damped while the losses are low for TE modes comprising a node at the position of the composite metal film(s). The possibility to control the effective refractive index and the losses for individual hybrid plasmonic-dielectric TM and dielectric TE modes opens new design opportunities for mode selective waveguides and TM-TE mode couplers.
