• Heterogeneous integration of Si photodiodes on silicon nitride for near-visible light detection OPTICS LETTERS Cuyvers, S., Hermans, A., Kiewiet, M., Goyvaerts, J., Roelkens, G., Van Gasse, K., Van Thourhout, D., Kuyken, B. 2022; 47 (4): 937-940

  Abstract

  Silicon nitride (SiN) is used extensively to complement the standard silicon photonics portfolio. However, thus far demonstrated light sources and detectors on SiN have predominantly focused on telecommunication wavelengths. Yet, to unlock the full potential of SiN, integrated photodetectors for wavelengths below 850 nm are essential to serve applications such as biosensing, imaging, and quantum photonics. Here, we report the first, to the best of our knowledge, microtransfer printed Si p-i-n photodiodes on a commercially available SiN platform to target wavelengths <850 nm. A novel heterogeneous integration process flow was developed to offer a high microtransfer printing yield. Moreover, these devices are fabricated with CMOS compatible and wafer-scale technology.
