A planar lightwave circuit comprising: a substrate; an optical waveguide; a trench cut in the substrate opposing a face of the optical waveguide, the trench comprising a sloped wall exhibiting an oblique angle with a center axis of the optical waveguide, the sloped wall opposing the face of the optical waveguide; and an optical element having an active optical area, the optical element being secured on the sloped wall such that the active optical area faces the optical waveguide at the oblique angle. Preferably the oblique angle is between 5°-85°, and even further preferably between 30°-70°. |
