Near infrared microcoupler with multilayer isotropic metamaterials Academic Article uri icon

abstract

  • This paper reports the design of a microcoupler in the near-infrared region. The proposed structure consists of two alternately arranged complementary media. The complementary media, which consist of double-positive material and double-negative material, also can be made of a pair of single-negative materials. Simulation results show that the proposed structure has an excellent coupling efficiency compared to direct coupling. It has a maximum coupling efficiency closing to 1 at 1550nm. As the total size of the coupling structure decreases, the passband exhibits a property of gradual blue shift. Therefore, we can design couplers operating in different frequency bands with high coupling efficiency. The influence of the permittivity and the thickness of each material layer on the coupling efficiency are also studied in detail. The proposed microcoupler has potential guidance in the design and development of high-performance coupling structures.
