    Abstract: Provided is an optical coupler including a substrate, a buffer layer on the substrate, a ridge waveguide having a first side surface and a second side surface opposed to the first side surface, and a first waveguide disposed adjacent to the second side surface. The first waveguide includes a first body part and a first connecting part extending from one end of the first body part to be inserted in the ridge waveguide. The first connecting part has a width decreasing in the direction away from the second side surface, and the ridge waveguide includes an extension part extending under an upper surface of the buffer layer.

    Abstract: An optical coupling device comprises an optical fiber block including a first block part and a second block part contacting with one side of the first block part, an optical fiber penetrating the optical fiber block and having an end surface exposed at a bottom surface of the optical fiber block, a semiconductor chip disposed below the optical fiber block and having an optical input/output element disposed on a top surface of the semiconductor chip to correspond with the end surface of the optical fiber, and a planarization layer disposed on the top surface of the semiconductor chip and having a recess region. A bottom surface of the first block part has a higher level than that of the second block part. The bottom surface of the second block part contacts with a bottom of the recess region. The optical fiber is optically coupled with the optical input/output element.

    Abstract: Provided are an optical coupler and an arrayed-waveguide grating structure including the same. The coupler includes a lower clad layer, a core comprising a slab waveguide region disposed on one side of the lower clad layer and a ridge waveguide region disposed on the other side of the lower clad layer, and an upper clad disposed on the core, wherein the ridge waveguide region comprises a self-focusing region configured to focus an optical signal provided form the slab waveguide region and thus to prevent scattering of the optical signal.
