摘要

Lasers based on In(AlGaAs)P materials emitting in the optical c-band are heterogeneously integrated onto Si substrates by Micro Transfer Printing (μTP). Efficient thermal sinking allows the lasers to operate in continuous wave up to 45°C. The reflectivity at the facets can be optimized by tuning the thickness of the passivation layer. This integration strategy can be particularly relevant for lasers being coupled to polymer or SOI waveguides for advanced photonics integrated circuits.
