- Provided are an optical coupler and an optical device including the same. The optical coupler includes: a substrate; a buffer layer on the substrate; and an optical coupling layer including a horizontal mode expander layer and a vertical mode expander layer, wherein the horizontal mode expander layer expands in one direction on the buffer layer, and wherein the vertical mode expander layer adjusts a stepped difference between the horizontal mode expander layer and a plurality of optical transmission devices having different diameters or sectional areas and connected to both sides of the horizontal mode expander layer, and the vertical mode expander layer is disposed on a side of the horizontal mode expander layer to minimize optical loss between the plurality of optical transmission devices.
