Date Oct. 28, 1993.A method is proposed for producing passive and/or
active optical polymer components having integrated fibre-chip coupling
by means of casting technology. For this purpose, the master structure
is produced in common on a silicon substrate both for accommodating an
optical waveguide and a fibre-guiding structure anisotropically etched
into the substrate [sic], this master structure is cast by
electroplating and the negative mould thus produced is used to produce
daughter structures identical to the master structure, the
anisotropically etched V-shaped positioning trenches being filled with
polymer materials, so that a planar surface is produced, the planar
surface is coated with a photoresist or another structurable polymer,
trench-shaped openings which subsequently produce the optical
waveguides are structured into the polymer coating, and the trench
structures are opened by means of laser ablation.
