Abstract
The invention relates to an electro-optical arrangement for coupling light signals into an optical waveguide, which has a laser diode for emitting light signals and a microlens, which focuses light signals emitted by the laser for coupling into the optical waveguide. According to the invention, the microlens is arranged on a carrier carrying the laser diode.
