Silicon photonics is critical for next generation cost-effective, energy-efficient optical interconnects. Much progress has been made. However, one most critical component remains missing: a CMOS-compatible laser. In this talk, I will discuss a completely new growth mode that enables metastable synthesis of single crystal III-V nanomaterial on silicon and poly-silicon. I will discuss characteristics of avalanche photodetectors, photovoltaic devices and light emitting diodes fabricated using III-V nanopillars directly grown on silicon. In addition, I will discuss characteristics of optically-pumped nanolasers grown on Si-MOSFET
