Integrated photonics was rejuvenated as Si starting off hard the dominant situation of conventional III-V compound semiconductors at onset of the new millennium. Heterogeneous Si photonics utilizes wafer bonding to transfer functioning non-Si slim movie on to Si substrate to make up lacking or weak optoelectronic functionalities of Si materials. In the previous 15 many years, it has advanced into a wide engineering with numerous branches as proven in Fig. 1. As the most mature just one among them, heterogeneous III-V-on-silicon integration gives an ideal platform to marry their respective materials and manufacturing benefits. Two veteran scientists in this discipline, Dr. Di Liang from Hewlett Packard Labs and Prof. John Bowers from College of California – Santa Barbara, carefully reviewed a variety of current breakthroughs to demonstrate how this novel concept has progressed from a science task 15 many years ago to a developing enterprise and compelling exploration field currently. It contains each business successes in significant-volume optical transceiver merchandise for details middle interconnect application and new study directions in resources, system layouts and integration system innovations. Long term progress perspectives ended up reviewed at the conclude to inspire additional technological developments in academia and marketplace.
