Abstract

The study of a monolithic multisection modelocked laser for millimetre (mm)-wave radio-over-fibre (RoF) links is reported. The longitudinal mode spectrum is studied, as is the evolution of the mode distribution with the injected current in the different sections. A stable dual-mode operation regime is identified and used to demonstrate the possibility of using this device as a compact transmitter in RoF systems incorporating optoelectronic upconversion through the injection of an intermediate frequency signal in the absorber section, while the 40GHz mm-wave carrier is injected in the gain section. Characterisation of the modelocked laser in an analogue transmission experiment shows a spurious free dynamic range of 65dB-Hz 2/3 .
