Abstract

We present the first demonstration of the generation of single sideband (SSB) modulation using a monolithic integrated electro-absorption modulated laser (EML) device. Suppression of upper or lower sidebands is observed under synchronous dual analog narrow band driving of the laser and the modulator sections. The 10 GHz carrier can transport digital format data for a wide variety of Radio-over-Fiber (RoF) transmission systems. A 50 MBaud/s transmission of a 16-QAM signal has been achieved over 150 km of Standard Single Mode (SMF) fiber. Constellations, eye diagrams and error vector magnitude (EVM) measurements are presented, all of which are temperature independent up to 45°C. This demonstration of SSB modulation capability, which allows for signal transmission with a high spectral efficiency, free of side-band beating and with a uniform signal power over the entire length of the optical fiber, makes the device ideal for use in both optical metropolitan and optical access networks. Our experimental results establish the dual-EML SSB transmitter as a serious candidate for optical-wireless network convergence and future OFDM systems.
