The Developement of GaN Based High-Speed Green and Cyan Light Emitting Diodes for Plastic Optical Fiber Communication

摘要

We review our work on GaN based green light-emitting diodes (LEDs) for plastic optical fiber (POF) communication. By downscaling device active volumes with optimized doping profile, record-high electrical-to-optical bandwidth (0.4 GHz) among visible LEDs under a moderate bias current (40 mA) can be achieved. By use of packaged LED, 1 Gbit/sec data transmissions over 50 meter POF have been achieved. Such result is comparable with those of the high-performance red resonant cavity LED under the same bias current (40 mA).
