A light-controlled frequency-shift keying modulator for a fibre-optic wireless broad-band download system using millimetre waves has been investigated. In it, intensity-modulated infrared signals are adopted for modulating the carrier frequency of the 37 GHz band. The modulation principle is based on the impedance change under illumination in an InP-based millimetre-wave monolithic integrated circuit oscillator. Using the modulator, fibre-optic wireless transmission with a bit error rate of 10−11 was obtained at a data rate of 155.52 Mbit/s.
