Broadband sharp 90-degree bends and T-splitters in plasmonic coaxial waveguides.
We demonstrate numerically that sharp 90° bends and T-splitters can be designed in plasmonic coaxial waveguides at deep-subwavelength scale to operate without reflection and radiation over a broad range of wavelengths, including the telecommunication wavelength of 1.55 μm. We explain the principles of the operation using a transmission line model of the waveguide in the quasi-static limit. The ...
متن کاملBends and splitters in graphene nanoribbon waveguides.
We investigate the performance of bends and splitters in graphene nanoribbon waveguides. Although the graphene waveguides are lossy themselves, we show that bends and splitters do not induce any additional loss provided that the nanoribbon width is sub-wavelength. We use transmission line theory to qualitatively interpret the behavior observed in our simulation. Our results pave a promising way...
متن کاملjp 3 D waveguides with fiber couplers and 90 degree bends in holographic photopolymer
Two active areas of research in the field of integrated optics are the coupling of on-chip waveguides to off-chip optical fibers and the reduction of circuit size which is dominated by the minimum bend radius of waveguides. Traditional approaches using mask-based lithography involve the complex etching of micro-mechanical on-chip mounts for the fiber or total-internal-reflection facets for shar...
متن کاملHigh Transmission through Sharp Bends in Photonic Crystal Waveguides.
We demonstrate highly efficient transmission of light around sharp corners in photonic bandgap waveguides. Numerical simulations reveal complete transmission at certain frequencies, and very high transmission s.95%d over wide frequency ranges. High transmission is observed even for 90± bends with zero radius of curvature, with a maximum transmission of 98% as opposed to 30% for analogous conven...
متن کاملSharp bends in photonic crystal waveguides as nonlinear Fano resonators.
We demonstrate that high transmission through sharp bends in photonic crystal waveguides can be described by a simple model of the Fano resonance where the waveguide bend plays a role of a specific localized defect.We derive effective discrete equations for two types of the waveguide bends in two-dimensional photonic crystals and obtain exact analytical solutions for the resonant transmission a...
