PCT No. PCT/DE93/00475 Sec. 371 Date Dec. 6, 1994 Sec. 102(e) Date Dec. 6, 1994 PCT Filed Jun. 3, 1993 PCT Pub. No. WO93/25924 PCT Pub. Date Dec. 23, 1993.An integrated-optical device in polymer technology, having a photoelement coupled onto an optical waveguide, with only the evanescent field components of the optical waveguide being coupled by an optical coupling element into the photoelement, wherein the photoelement (23) is incorporated into a polymeric upwardly closed cover plate (51), the cover plate (51) is fitted exactly onto a base plate (50) having an optical waveguide (20), and the coupling element is an optical buffer layer (54) disposed between the cover plate (51) and base plate (50). Preferably, the buffer layer (30) has a refractive index in the region opposite the photoelement (23) which is less than or equal to the refractive index of the optical waveguide (20), but greater than the refractive index of the buffer laser (30) outside the region opposite the photoelement (23).
