Abstract

In this paper, we perform a frequency up-conversion from 4.5 GHz to 60 GHz of an OFDM signal compliant to the IEEE802.15.3c pre-standard (3.03 Gbps) by directly modulating a Fabry-Perot mode-locked laser whose self-pulsating frequency is 54.8 GHz. Improved performance compared to the external modulation scheme previously reported is achieved and comparison with the use of a standard electronic up-converter shows only a slight degradation. The direct modulation represents a major improvement in terms of set-up simplicity and improves the efficiency of the conversion process. It does not degrade the phase noise properties of the photonic oscillator. This simple set-up allows as well the distribution (over 50 m) of the 60 GHz radio signal using radio-over-fibre. Transmission of the up-converted signal over 5 m of air does not show any significant degradation.

60 GHz无线电信号的上转换和传输使用直接调制锁模激光

本文通过直接调制自脉冲频率为54.8 GHz的Fabry-Perot锁模激光器，实现了符合IEEE802.15.3c预标准(3.03 Gbps)的OFDM信号从4.5 GHz到60 GHz的频率上变频。与先前报道的外部调制方案相比，性能得到了改善，与使用标准电子上变频器相比，性能仅略有下降。直接调制在设置简单性和提高转换过程的效率方面取得了重大进步。它不会降低光子振荡器的相位噪声特性。这种简单的设置也允许分布(超过50米)60千兆赫的无线电信号使用光纤上的无线电。在5米的空气中传输上转换信号没有表现出任何明显的退化。
