Modulation of injection heterolaser radiation with a Gunn diode

A Gunn diode was used to modulate at about 1 GHz the radiation emitted by an injection laser with a double-sided heterostructure. An analysis of the operation of this system was made. It was found that one Gunn diode could modulate several tens of injection lasers. The output power and efficiency increased with the number of such lasers and the power rose faster than the number of the lasers.
