Abstract
A coupling technique for the side coupling of light from a light source into a waveguide is provided. A transversal groove is made into a section of the waveguide, extending into the target light guiding region. A coupling element is coupled to the light source at one of its end to receive the light beam therefrom. The opposite end of the coupling element is inserted in the groove and has at least one reflecting interface which specularly reflects the light beam for propagation into the waveguide. This technique may advantageously be used to couple light from the laser diodes of an array into one or a plurality of optical fibers.
