Dominant Foot – “Right Footed” The human body is made up largely of paired structures, most of which are not perfectly matched. Stated differently, the apparent mirror image symmetry of the human body (arms, legs, face, eyes) is in reality an array of asymmetrical parts. It is this fundamental asymmetry that leads to the concept of dominance. For example, most people have a dominant arm and han...

We present theory and experiment for high-speed optical injection in the absorption region of a quantum-well laser and compare the results with those of the electrical injection in­ cluding carrier transport effect. We show that the main difference between the two responses is the low-frequency roll-off. By using both injection methods, we obtain more accurate and consistent measurements of man...
