Abstract

Future in-house Multimedia networks, based on the IEEE 1394b standards, require low cost and robust optical transmission system in the range of 100 meter. In this paper, we presented the state of the art 650 nm micro-cavity light emitting diodes (RCLEDs) for such application. We had made RCLEDs with diameters of the emission window of 84, 60, 40μm for different requirements. Because of excellent epitaxy quality and structure design. Our RCLEDs perform record high power and efficiency. With expoxy encapsulated, the 84μm devices give an efficiency of 12% and yield more than 3.5mW at operation current 20mA. Our 40μm devices exhibit high small-signal modulation-bandwidths (f_-3D) as 310MHz at bias current of 20mA. The output power of 40μm devices is still as high as 1.5mW, which is suitable for IEEE 1394b s400 standard. On the other hand, we had developed metal bonding RCLEDs (MBRCLEDs) to improve the high temperature performance of RCLEDs. By proper design the structure and process, the MBRCLEDs can have very low power decay as 0.6dB from 20°C to 100°C.
