Paper Abstract

The potential use of two-section gain-coupled distributed feedback lasers as a source for the generation and distribution of millimeter-wave signals for wireless applications is demonstrated. First we report on the dependence of the tuning range on the device structure and the use of two injection techniques to reduce the linewidth of the millimeter-wave signals generated at 40GHz. The first technique is self sub-harmonic injection locking using a 5GHz signal and the second is direct side-band injection locking using a 20GHz to lock a 40GHz signal. The phase noise is measured and the jitter is calculated. Secondly the fiber-based network architecture of a wireless system based on the two-section DFB laser is proposed. The aim of the networks is to expand the bandwidth for each base station, maximize sharing of the mm-wave source and fiber, reduce the number of active devices at the base and the mobile unit, and expand the role of photonics in the network design. The system we propose is WDM-SCM network architecture.
