    Abstract: Provided are a waveguide with a reduced phase error and a photonics device including the same. The waveguide structure may include a lower clad, a core pattern with at least one bending region, on the lower clad, a beam deflecting pattern on the core pattern, and an upper clad covering the core pattern provided with the beam deflecting pattern. The beam deflecting pattern may be formed of a material, whose refractive index may be higher than that of the upper clad and may be lower than or equivalent to that of the core pattern, and the beam deflecting pattern has an increasing and decreasing width or an oscillating width, when measured along the bending region.

    Abstract: An optical filter of the inventive concept includes a slab waveguide disposed on a substrate, an input guide gate and an output guide gate spaced apart from each other in the slab waveguide, and an echelle grating filter disposed in the slab waveguide. The echelle grating filter has curvature and extends in a first direction. The echelle grating filter has gratings of sawtooth shape on one surface thereof. Light inputted through the input guide gate is totally reflected at the echelle grating filter by one reflecting process.
