"Optical Device" W. Pernice, C. Schuck, F. Beutel, N. Walter, H. Gehring, W. Hartmann, M. Wolff DE Patent No. DE102019009399B4 (granted Feb. 01, 2024)
Inventors: Wolfram Pernice, Carsten Schuck, Fabian Beutel, Nicolai Walter, Helge Gehring, Wladick Hartmann, Martin Wolff
Abstract: In an optical device for bidirectional coupling of a waveguide to an external medium, the coupling bandwidth of the optical device is to be broadened so that a wide spectrum of wavelengths can be coupled into an external medium through the optical device. This is achieved by the optical device comprising at least one taper structure, wherein the taper structure includes a beam input segment, the beam input segment being arranged to couple a light beam from the waveguide into the taper structure. The taper structure includes a beam output segment, the beam output segment being arranged to focus the light beam and couple it into the external medium. The taper structure between the beam input segment and the beam output segment includes at least a first reflective surface, the first reflective surface being arranged to deflect the light beam out of the plane of the waveguide, characterized in that the waveguide is designed as a freestanding waveguide arm.
