Abstract (en)
[origin: WO2020245259A1] In an optical device for bidirectional coupling of a waveguide (7) to an external medium (6), the aim of the invention is to widen the coupling bandwidth of the optical device, so that a wide spectrum of wavelengths can be coupled into an external medium via the optical device. This aim is achieved in that the optical device comprises at least one taper structure (2), the taper structure (2) comprising a beam entry segment (3), the beam entry segment (3) being designed so as to couple a light beam (5) from the waveguide (7) into the taper structure (2), and the taper structure comprising a beam exit segment (4), the beam exit segment (4) being designed so as to focus the light beam (5) and to couple same into the external medium (6), the taper structure (2) comprising at least one first reflective surface (8) between the beam entry segment (3) and the beam exit segment (4), and the first reflective surface (8) being designed so as to deflect the light beam (5) out of the plane of the waveguide (7).
