Abstract
Magnetically stored data, for example data stored on a magnetic tape is converted directly into optical signals by an arrangement which comprises a magneto-optical modulator and a wave guide laser. The wave guide laser has an index of refraction n.sub.2 and is arranged on a transparent substrate which has an index of refraction n.sub.3 by epitaxial growth. The magneto-optical modulator has an index of refraction n.sub.1 and is applied as an epitaxial growth to the wave guide laser. The indices of refraction fulfill the condition that n.sub.1 > n.sub.2 > n.sub.3.
