TL;DR: In this paper, the authors review the work on heterogeneous III-V-on-silicon photonic components and circuits for applications in optical communication and sensing and elaborate on the integration strategy and describe a broad range of devices realized on this platform.

TL;DR: In this article, a hybrid laser is described for generating radiation, the hybrid laser (100) comprising an optical passive material (110) and an optical active material (120), and furthermore comprises a first optical waveguide (112) and optical laser components (114) comprising reflectors in the optical passive materials (110).

TL;DR: The backreflection in commonly used grating couplers on silicon-on-insulator (SOI) is dramatically reduced in the improved compact grates coupler design, which directs the reflection away from the input waveguide.

TL;DR: In this paper, hybrid silicon lasers based on bonded III-V layers on silicon are discussed with respect to the challenges and trade-offs in their design and fabrication and specific designs that combine good light confinement in the gain layer with good spectral control provided by grating structures patterned in silicon.

TL;DR: The presented coupler is expected to pave the way to integrating III-V lasers monolithically grown on SOI wafers with other photonics components, one step closer towards a fully functional silicon photonics platform.
