Abstract :
Summary form only given. Millimeter (mm)-wave wireless systems will provide a versatile final drop for future broadband FTTX networks. The mm-wave EO conversion using the external modulation of laser light is promising due to the high spectral purity directly inherited from low noise light sources as well as its simplicity compared to optical heterodyning techniques. However, the highest radio frequency (RF) of the external modulation so far achieved has been limited to 40 GHz. This paper presents error-free optical 156-Mbit/s mm-wave wireless transport by using a 60-GHz external modulator.
