A waveguide for the extraction of light at low levels of reflection arranged to guide light from an electro-optical component on a chip to a facet on the chip for extraction includes a first part and a second part. The first part () is extended, the second part () includes a surface (JK) through which the light exits from the waveguide (). A non-adiabatic longitudinal section (GHLM) is located after the first part () but before the surface (JK) in the direction of propagation of the light, and the surface (JK) forms in the plane of the chip a first angle (V) with the optical axis (A) of the first part () that lies between 5 and 80 degrees.
