This letter describes the experimental results of an optical transmission link with modulation rates up to 4 GHz. The transmitter consists of an FET driven GaAlAs injection laser emitting at a 8500 Å wavelength. The receiver makes use of a GaAs MESFET chip which is compared with a standard silicon avalanche photodiode demodulator.
Osterwalder et al. (1979) studied this question.
