Abstract
Integrated photonics, particularly Silicon-based photonics, is a disruptive technology reshaping the landscape of optical communication in the past 10 years. A marriage of silicon and other functioning photonic materials, e.g., compound semiconductors, through heterogeneous integration results more than just combining complementary merits of different material systems. As the world is embracing a new AI era, heterogeneous integrated photonics with broader versatility has potential to trigger huge impact in communications and computing in AI clusters. I will attempt to elaborate this with examples of heterogeneous integration-enabled key photonic devices, densely integrated photonic circuits, new functionalities, and emerging applications.
