Researchers Design Heterogeneously Integrated III-V Laser on Thin SOI

Experts agree, light-based communication technology and optical data storage of the future will rely on III–V silicon on-chip lasers. A prerequisite for these lasers is to confine light for maximum efficiency and couple light with optical waveguides.

Researchers at the A*STAR Data Storage Institute (DSI) have now designed a compact III–V silicon laser that does both. With two tapered ends, the structure realizes efficient lasing through the smart control of light — light is tightly confined to the III–V semiconductor layer where lasing occurs. Furthermore, both laser ends are tapered to facilitate the coupling of light with underlying silicon waveguides.
