ABSTRACT:
An optical fiber having an a core with a D-shape or an oval shape at an endface. The optical fiber tapers from a round, cylindrical section to the endface so that adiabatic mode transformation is provided. Preferably, the D-shape or oval shape is selected so that the optical fiber has a mode shape at its endface that matches the mode shape of a diffused waveguide.
