Abstract
This work presents photonic integrated multi-channel transmitters for free-space optical communication systems applications. The circuits were designed and fabricated using the generic indium phosphide technology, which offers integration of passive and active elements and light amplification within the classical telecom C and L bands. The transmitters comprise an array of DBR laser light sources connected to electro-absorption modulators and an arrayed waveguide grating used as a wavelength multiplexer. The validity of the applied solution was investigated and confirmed with high-speed transmission experiments, including BER and eye diagram measurements of one and two-channel operations. The performance of the transmitters has been verified in the back-to-back configuration, and the first tests of free-space optical transmission have also been performed. The obtained results confirm the applicability of integrated transmitters in novel FSOC systems.
