- Abstract
- An optical device according to the embodiment of the inventive concept includes a waveguide path including a light generation region, a wavelength variable region, and a light modulation region, a first light waveguide layer provided in the light generation region to generate light, a second light waveguide layer provided in the wavelength variable region and connected to the first light waveguide layer, a ring-shaped third light waveguide layer provided in the light modulation region and connected to the second light waveguide layer, and first and second light modulation electrodes spaced apart from each other with the light modulation region therebetween. Here, the first light modulation electrode, the third light waveguide layer, and the second light modulation electrode vertically overlap each other.
