Abstract :
We show theoretically that resonant modulation at millimeter wave frequencies of inhomogeneously biased monolithic quantum-well laser diodes provides an enhancement in the modulation efficiency of >14 dB over that of the homogeneously biased laser, accompanied by a corresponding 7 dB increase in the noise and a comparable decrease in the signal-to-intermodulation distortion. We derive simple expressions for the enhancement in the modulation efficiency, the noise and intermodulation distortion, and discuss the limits of this approach and the trade off between these quantities. The theoretical results presented here are in good agreement with recently published experimental work.<>
