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 40 GHz 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 65 dB-Hz2=3.
