WebJan 27, 2024 · [email protected]. 1/27/2024. Radio frequency (RF) and microwave signals invisibly permeate the environment around us, carrying everything from radar signatures to the data from our mobile phones. Within RF systems, electronic oscillators can act as precise clocks or directly generate the baseline microwave tones. WebWe present an experimental investigation on the period-one dynamics of an optically injected InAs/GaAs quantum dot laser as a photonic microwave source. It is shown that the microwave frequency of the quantum dot laser’s period-one oscillation is continuously tunable through the adjustment of the frequency detuning. The microwave power is …
