A highly efficient electrically pumped optical amplifier integrated on a SOI waveguide circuit

摘要

A heterogeneously integrated III–V-on-silicon optical amplifier utilizing an ultra-thin DVS-BCB die-to-wafer bonding process is reported. A novel design exploiting high confinement in the active waveguide is demonstrated showing low power consumption operation. 13dB on-chip gain is achieved for 40mA drive current at room temperature.
