2 μm wavelength range InP-based type-II quantum well photodiodes heterogeneously integrated on silicon photonic integrated circuits
Open accessAbstract
The heterogeneous integration of InP-based type-II quantum well photodiodes on silicon photonic integrated circuits for the 2 µm wavelength range is presented. A responsivity of 1.2 A/W at a wavelength of 2.32 µm and 0.6 A/W at 2.4 µm wavelength is demonstrated. The photodiodes have a dark current of 12 nA at -0.5 V at room temperature. The absorbing active region of the integrated photodiodes consists of six periods of a "W"-shaped quantum well, also allowing for laser integration on the same platform.

The WG-QDPD results are on par with the best-performing bonded III-V photodetectors reported in the literature (responsivity 0.4-1.4 A/W around 2.3 μm and dark current 10 nA-2.5 μA).
“Notably, these results are on par with the best-performing bonded III-V photodetectors reported in the literature (responsivity 0.4-1.4 A/W around 2.3 μ m and dark current 10 nA-2.5 μ A), 6-9 outperforming monolithically grown GeSn (responsivity < 0.52 A/W and dark current > 1 mA). 13-16”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
