A semiconductor optical amplifier at 2.0-mu m wavelength is reported. This device is heterogeneously integrated by directly bonding an InP-based active region to a silicon substrate. It is therefore compatible with low-cost and high-volume fabrication infrastructures, and can be efficiently coupled to other active and passive devices in a photonic integrated circuit. On-chip gain larger than 13 dB is demonstrated at 20 degrees C, with a 3-dB bandwidth of similar to 75 nm centered at 2.01 mu m. No saturation of the gain is observed for an on-chip input power up to 0 dBm, and on-chip gain is observed for temperatures up to at least 50 degrees C. This technology paves the way to chip-level applications for optical communication, industrial or medical monitoring, and non-linear optics.
