Heterogeneous integration of III–V on Silicon based microlaser sources for photonic integrated circuit applications

Large scale integration of optical functions on Silicon has become of a great interest in the last years. Through heterogeneous integration of III-V materials on Silicon, new building blocks are currently studied. An important issue is the development of efficient laser sources, for both guided and free space emission. Low threshold combined to small footprints are required for silicon photonics applications. In this work, we will explore two microsources concepts: a refractive approach with microdisk based sources and a diffractive approach using photonic crystal (PC) sources.
