Abstract: An optical waveguide structure includes a substrate and a core structure disposed on the substrate. The substrate includes a first waveguide region, a second waveguide region, and a transition region between the first waveguide region and the second waveguide region. The core structure includes first core segments arranged in a first direction and a second direction crossing the first direction on the transition region. The core structure includes second core segments arranged in the first direction and the second direction on the second waveguide region. The first direction and the second direction are parallel to a top surface of the substrate.

Abstract: Disclosed is a planar waveguide element including a first cylindrical lens disposed based on an z-axis and configured to collimate beams emitted from a plurality of emitters of a laser diode bar; a lens array configured to gather the beam emitted from each emitter via the first cylindrical lens; a plurality of first waveguides existing on an x-y plane by a number of the plurality of emitters and configured to gather at one place via a bending section; a taper configured to connect the lens array and each first waveguide, a width of the taper being narrower from the lens array to the plurality of first waveguide; and a combined waveguide configured to combine the plurality of first waveguides into one.
