High-Performance Silicon Photonics Using Heterogeneous Integration

The performance of silicon photonic components and integrated circuits has improved dramatically in recent years. As a key enabler, heterogeneous integration not only provides the optical gain which is absent from native Si substrates enables complete functionalities on chip, but also lays foundation versatile device engineering. This paper reviews progress high-performance photonics using integration, with emphasis ultra-low-loss waveguides, single-wavelength lasers, comb including phased arrays for LiDAR transceivers datacenter interconnects.
