摘要：
In this paper we review the recent development of resonant cavity light emitting diodes (RC-LEDs), intended for short-haul polymer optical fibre (POF) data transmission systems. The RGLEDs with emission windows of circle divide84 mum in diameter, suitable for standard POFs, exhibit bandwidths up to 200 MHz and light power of 3 mW (cw). The maximum external quantum efficiency is 9.5%. Larger devices, 0500 mum in size, launch light power up to 15 mW. Record high transmission rates, 622 Mbit s(-1), with bit-error rate < 1 x 10(-11) have been demonstrated for a 1 m long step-index POF. The devices are robust. Neither sudden unexpected failure, nor gradual power degradation has been observed after operation under accelerated ageing conditions for about 100 000 device-hours. The alignment tolerance of the coupling efficiency is found to be very large, +/-0.5 mm in all x-y-z, directions, suggesting that fibre pigtail packaging is inexpensive.
