Abstract
Official abstract text for this publication.
Integrated upconversion devices capable of upconverting incident visible to short wavelength infrared photons to visible photons are disclosed. The device may include a quantum dot-based photodiode and a light-emitting diode. The device may further include a gain element such as a thin-film transistor.
First claim
Opening claim text (preview).
What is claimed is: 1. An upconversion device, comprising: a thin-film photodiode (PD) comprising a PD cathode, a PD anode, and a PD active region between the PD anode and the PD cathode, wherein at least one of the PD cathode and the PD anode is transparent to incident photons in the short-wavelength infrared (SWIR) or SWIR-visible range, and the PD active region comprises a quantum dot (QD) layer and is configured for outputting an electrical signal in response to receiving the…
