Abstract
The techniques used for the fabrication of photonic integrated circuit (PIC) chip are introduced briefly. Then a four channel DFB laser array integrated with MMI coupler and semiconductor optical amplifier (SOA) fabricated with butt-joint technique, varied ridge width and holographic exposure techniques is reported.
