Abstract

As the frequency spectrum below 10GHz becomes saturated, it will become increasingly difficult to maintain adequate bandwidth provision for the growing customer demand. For this reason, the possibility of utilizing the unlicensed 57GHz – 64GHz band for services such as WPAN is an attractive prospect [1]. Furthermore, the advantages of an optical system to realize this prospect are numerous. Extremely low phase noise can be obtained from laser systems used for millimetre-wave applications, relative to the equivalent electronic components. In addition to this, the costs of such a system are much lower and the footprint smaller, not to mention the additional benefits of low loss and easy switching of carrier frequency.
