Abstract :
The authors demonstrate a continuously tunable optoelectronic transmitter which uses a monolithic mode-locked semiconductor laser. Millimetre-wave subcarrier frequencies up to 300 GHz can be generated by photomixing a microwave subcarrier frequency with the selected harmonics of the mode-locked frequency, using an electro-optic modulator. A subcarrier frequency which can be tuned continuously from DC to 43 GHz is achieved experimentally
