Organic optocouplers

Organic optocoupler (OOC) or organic photocoupler, optical coupler is a novel and one of the most promising organic optoelectronic devices for its well electrical isolation and anti-jamming ability in long-distance and real-time digital communications. The performance parameters of OOC were greatly raised during the past decade, and its development was strongly associated with basic organic devices such as organic light emitting diodes (OLED), organic photodiodes (OPD) and organic phototransistors (OPT) etc. Here we describe the principles of OOC, review recent breakthroughs in this field, and summarize the photosensor and light emitting parts which could be used in the device. Key technical points, such as current transfer ratio, frequency, matching and stability were also discussed in this paper.
