| 摘要 |
An optical device includes a silicon waveguide core having a tapered portion having a sectional size that decreases toward a terminal end portion thereof, a dielectric waveguide core contiguous to the silicon waveguide core while covering at least the tapered portion, the dielectric waveguide core having a refractive index lower than that of the silicon waveguide core and configuring a single-mode waveguide, and a diffraction grating provided at the single-mode waveguide and configuring a distributed Bragg reflection mirror. |

1. An optical device, comprising:
a silicon waveguide core having a tapered portion having a sectional size that decreases toward a terminal end portion thereof; a dielectric waveguide core contiguous to the silicon waveguide core while covering at least the tapered portion, the dielectric waveguide core having a refractive index lower than that of the silicon waveguide core and configuring a single-mode waveguide; and a diffraction grating provided at the single-mode waveguide and configuring a distributed Bragg reflection mirror. |
