Cost-efficient DWDM-PON/Mm-Wave wireless integration using coherent radio-over-fiber (CRoF)

This work aims to investigate the performance of millimetre wave (mm-wave) broadband wireless access for seamless integration with the (ultra-dense) WDM infrastructure. By using two uncorrelated lasers at the coherent receiver, a simple implementation is obtained, which can additionally be improved, if thermally uncooled lasers are used. Although such asynchronous receiver design is mildly affected by laser phase noise, it suffers from the wavelength drift that occurs between the uncooled laser sources. Also, there are performance penalties due to high laser line-width when complex modulation formats are used for transmission. In this work, we analyze the performance of heterodyne based optical receivers, using OOK and multilevel modulation formats.
