On-chip optical communications have experienced great progress lately, gaining in maturity with fast, reliable and efficient optical interconnects. Silicon photonics has demonstrated huge potential to become the dominant technology to support this development. Still, the silicon photonics lacks of a monolithic light source. To overcome this blocking point, hybrid integration of III-V materials on silicon raises as a viable route in the short term.
In this work, we will revisit the hybrid III-V on Si platform and put forward our particular vision at the III-V lab, discussing several points that will play a key role in the coming years.
