Abstract
This paper introduces a radio-over-fiber (RoF) architecture for transmission of 60-GHz multi-gigabit millimeter wave (mmWave), emitted by two different sources, a vertical cavity surface emitting laser (VCSEL) and distributed feedback (DFB) laser connected with electro-absorption modulator (EAM) using wavelength-division multiplexing (WDM) technique. These light generation techniques are used for delivering in-building wireless personal area network (PAN). At centralized office (CO), data are modulated simultaneously over two light waves under one infrastructure that will provide a 60 GHz mmWave, which is a cost-effective and efficient system. Due to the use of dynamic integrated architecture, millimeter-wave radio-frequency (RF) component will reduce the cost at the central office. With the proposed system, acceptable bit error rate (BER) less than 10–9 with a reasonably good carrier suppression of 40 dB is achieved after modulation, which facilitates lower power consumption architecture. Hence our proposed system using VCSEL and DFB can be best suited for indoor communication in a power-efficient and cost-effective manner. The susceptibility scale for investigation of these light-waves comes under 3 dB.
