ABSTRACT An ultracompact polarization beam splitter (PBS) based on a dielectric-hybrid plasmonic-dielectric coupler is proposed. The device utilizes the polarization-dependent nature of hybrid plasmonic waveguides. By choosing proper waveguide parameters, a 2×5.1 μm2 PBS (including S-bends) with extinction ratios over 15 dB and insertion losses below 1.5 dB in the full C-band should be achievable. The effect of fabrication errors is also investigated.

    ABSTRACT: A compact silicon-based polarization splitter (PS) is proposed using a three-guide directional coupler composed of a silicon nanowire in the center and two horizontal/vertical hybrid-plasmonic waveguides (HPWs) at outer sides. Utilizing the evanescent coupling, the injected TE/TM modes in the central silicon nanowire can be only coupled to the horizontal/vertical HPWs, leading to the separation of input polarizations. Moreover, to improve the extinction ratio (ER), an S-bend connecting with the vertical HPW is employed. Results show that a coupling length of 6.5 (4.5) μm is achieved at the wavelength of 1.55 μm with ER and insertion loss of ~18.9 (15.2) dB and ~0.44 (0.89) dB for TE (TM) mode, and the bandwidths can cover the entire C-band for both polarizations. In addition, fabrication tolerances to the structural parameters are presented and field evolution through the designed PS is also demonstrated.

    ABSTRACT: In this letter, an ultra-compact plasmonic polarization beam splitter (PBS) is proposed and investigated by numerical simulations using the finite element method. The PBS is based on a three-core plasmonic directional coupler, which uses a long range surface plasmon polaritons waveguide as the middle waveguide to achieve polarization selective coupling. The calculations show that with proper structural parameters, the PBS with low insertion losses of 0.17 and 0.25 dB for TE and TM polarizations, respectively, and high extinction ratios of 20.17 and 19.83 dB for TE and TM polarizations, respectively, can be realized at a telecommunication wavelength of 1550 nm. Furthermore, an insertion loss ${<}{rm 0.5}~{rm dB}$ and an extinction ratio ${>}{rm 14}~{rm dB}$ can be realized across the entire $C$ -band for both TE and TM polarizations.

    ABSTRACT: Based on a transverse electric (TE)/transverse magnetic (TM) polarization diversity waveguide, we theoretically propose a TE-pass/TM-stop polarizer by etching a polarization dependent Bragg grating into the oxide layer of a silicon/thin SiO$_2$gap/metal cap hybrid plasmonic waveguide. The simulation results indicate that the device is characterized by high TE-transmission and large TM-reflection levels in a wide waveband from 1.48 to 1.7 μm combined with an excellent compactness (length less than 5 μm). Transmission and reflection extinction ratio are both larger than 17.1 dB in the 1.48–1.64 μm wavelength range, while losses are smaller than 1.36 and 0.69 dB for the TE and TM modes, respectively.
