By implementing SOAs that guide two waveguides through a single contact active section, we can reduce dimensions ofphotonic integrated circuits (Tics.) and decrea,ce the number of electrical contacts of current injection. In this paper we demonstrate linear 4-channel and 8-channel A WG-based lasers that take advantage of such SOAs. This resulted in a reduction of the required number of active regions and contacts by a factor Iwo. Measurements showed that these sources operate with an output power of I in W per A WG-channel and side-mode suppression ratio better than 40 dB. The lasers were fabricated in a multi-project wafer run on an indium phosphide (InP,) based generic photonic integration platform.
