Book excerpt: Integrated Lasers on Silicon provides a comprehensive overview of the state-of-the-art use of lasers on silicon for photonic integration. The authors demonstrate the need for efficient laser sources on silicon, motivated by the development of on-board/on-chip optical interconnects and the different integration schemes available. The authors include detailed descriptions of Group IV-based lasers, followed by a presentation of the results obtained through the bonding approach (hybrid III-V lasers). The monolithic integration of III-V semiconductor lasers are explored, concluding with a discussion of the different kinds of cavity geometries benchmarked with respect to their potential integration on silicon in an industrial environment. - Features a clear description of the advantages, drawbacks, and challenges of laser integration on silicon - Serves as a staple reference in the general field of silicon photonics - Focuses on the promising developments of hybrid and monolithic III-V lasers on silicon, previously unreviewed - Discusses the different kinds of cavity geometries benchmarked with respect to their potential integration on silicon in an industrial environment
