摘要:
摘要： We report a high-speed data transmission over a 1-mm diameter step-index polymer optical fiber (SI-POF) with GaN light-emitting diodes (LEDs) operating at 435 and 475 nm. The modulation bandwidths of the LEDs at 40 mA were 180 and 300 MHz, respectively. A maximum bit rate of 5.5 Gb/s was achieved with a 475-nm GaN LED at -1.8-dBm fiber-coupled power over a 1-m SI-POF employing 4-pulse-amplitude modulation format. Compared with the performance of a high-speed red resonant-cavity LED under the same test setup, the chromatic dispersion reduces the potential of the GaN LED-based system when the transmission distance is longer than 30 m. 其他題名： LPT 出版者： New York: IEEE 出版日期： 2014-12-15 出處： IEEE photonics technology letters, 2014-12, Vol.26 (24), p.2473-2475 資源來源： IEEE Electronic Library (IEL) 版權： Copyright The Institute of Electrical and Electronics Engineers, Inc.
