An Efficient Coupling Scheme Between Photonic Crystal Waveguides and Plasmonic Metal-Insulator-Metal Waveguides
In this study, an efficient bi-directional optical coupler has been proposed. Our approach involves the development of a novel mechanism aimed at coupling a plasmonic waveguide to a photonic crystal waveguide. The innovative design of the small-scale plasmonic-photonic crystal-plasmonic coupler (PW-PC-PW) facilitates optimal power transmission between these interconnected waveguides. To conduct comprehensive simulations of the plasmonic-photonic crystal-plasmonic waveguides, we employ the finite difference time domain (FDTD) method. By establishing a coupling between the photonic crystal and plasmonic structures, we achieve efficient signal transfer, thereby laying the foundation for the creation of diverse devices that amalgamate the advantages offered by plasmonic devices and photonic crystals. Consequently, the device outlined in this paper holds substantial promise as a pivotal component for various types of optical integrated circuit devices. The electromagnetic waves operating within this structure fall within the wavelength range of 1500 to 2050 nm, and the achieved transmittance value at a wavelength of λ = 1550 nm reaches an impressive 95%.
期刊介绍:
Plasmonics is an international forum for the publication of peer-reviewed leading-edge original articles that both advance and report our knowledge base and practice of the interactions of free-metal electrons, Plasmons.
Topics covered include notable advances in the theory, Physics, and applications of surface plasmons in metals, to the rapidly emerging areas of nanotechnology, biophotonics, sensing, biochemistry and medicine. Topics, including the theory, synthesis and optical properties of noble metal nanostructures, patterned surfaces or materials, continuous or grated surfaces, devices, or wires for their multifarious applications are particularly welcome. Typical applications might include but are not limited to, surface enhanced spectroscopic properties, such as Raman scattering or fluorescence, as well developments in techniques such as surface plasmon resonance and near-field scanning optical microscopy.
