Optical device using a plasmonic waveguide, and optical isolator |
| 摘要 |
An optical device having a plasmonic waveguide, in which the plasmonic waveguide has a layered structure of at least three layers that a ferromagnetic metal layer, a first dielectric layer, and a second dielectric layer are layered in this order, in which the first and second dielectric layers are layers that allow light to be transmitted therethrough, and in which a refractive index of the second dielectric layer is higher than a refractive index of the first dielectric layer; and an optical isolator, having the optical device. |

1. An optical device having a plasmonic waveguide, wherein the plasmonic waveguide has a layered structure of at least three layers in which a ferromagnetic metal layer, a first dielectric layer, and a second dielectric layer are layered in this order, wherein the first and second dielectric layers are layers that allow light to be transmitted therethrough, and wherein a refractive index of the second dielectric layer is higher than a refractive index of the first dielectric layer.
