Paper Abstract

This paper presents our research and development efforts in realizing and perfecting organic/inorganic photon upconversion devices for wavelengths from near infrared (1.5 μm) region to visible light (green). The basic idea is to integrate an InGaAs/InP photodetector with an organic light emitting diode (OLED), connected in series. The detected photocurrent drives the OLED to emit visible light, thereby achieving the wavelength conversion. We have adopted new strategies to improve the external device efficiency, including insertion of an embedded mirror and integration of a heterojunction phototransistor (HPT) and an OLED. As a result, infrared optical upconversion is demonstrated at room temperature with a built-in electrical gain of 15 from the HPT and an external upconversion efficiency that is improved by one order of magnitude.
