INTEGRATED OPTICAL UPCONVERSION DEVICES AND RELATED METHODS |
摘要 |
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. |

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 incident photons; and a thin-film light emitting diode (LED) electrically communicating with the PD and comprising an LED anode, an LED cathode, and an LED active region configured for outputting visible photons in response to receiving the electrical signal, wherein at least one of the LED anode and the LED cathode is transparent to the visible photons outputted by the LED active region. |
