Electro-optic devices for imaging systems using radio-over-fibre

This paper describes high-speed optical modulation and detection devices for radio-over-fibre (RoF) systems which can distribute millimetre-wave signals over optical fibres with low-loss, and RoF-based high-performance imaging systems which can be used for foreign object debris in runways or railways. High-speed and high-sensitivity photo-detection would be very important to achieve high-resolution imaging. We will share our recent research results on precise lightwave modulation techniques and on high-speed photodetectors using quantum dots.
