Abstract: We have studied characteristics of a 23-$\mu$m-diameter microdisk laser operating in a regime of direct high-frequency modulation at a stabilized heat-sink temperature of 18$^\circ$C. It is found that the minimum energy consumption in this regime amounts to $\sim$1.6 pJ/bit and is achieved at a modulation frequency of 4.2 GHz. The maximum modulation frequency is 6.7 GHz, at which the minimum energy consumption is 3.3 pJ/bit.

Keywords: high-frequency modulation, microlaser, diode laser, quantum dots, energy-to-data ratio.
