题目: Hybrid Organic/Inorganic Optical Upconversion Devices
The widely available charge coupled device (CCD) and lately CMOS imaging devices have created many applications on a mass scale. However these devices are limited to wavelengths shorter than about 1 μm. Hybrid photon upconversion devices have been developed recently. The end goal is to achieve an alternative technology for imaging in the 1.5-μm region. The hybrid upconversion idea relies on the integration of a III-V infrared photodetector and an organic light emitting diode (OLED). The integration of an OLED with a III–V compound semiconductor is a highly feasible and desirable approach for making low-cost, large-area, potentially high efficiency devices. In this talk, I will discuss the physics, fabrication and characterization of hybrid near infrared optical upconverters and their imaging application. The experimental results of the first organic/inorganic hybrid optical amplifier and the first hybrid near infrared imaging device will be presented. I will also briefly talk about my future research plan.
