Abstract

Two interacting lasers are useful as a computer element. Such an arrangement is used as an And with light output since the thresholds for stimulated emission for two interacting simultaneously driven lasers is less than the threshold of each individually.

Structure of Two Interacting Lases

Two interacting lasers are useful as a computer element. Such an arrangement is used as an And with light output since the thresholds for stimulated emission for two interacting simultaneously driven lasers is less than the threshold of each individually.

Coupled lasers are constructed, as shown, in such a way that the interaction is maximized. In this structure, a small region halfway along its length is masked against the diffusion of the acceptor impurity, resulting in two separate co-planar junctions. The separation of the junction into two regions can also be achieved by a heavy N-type diffusion into the center region instead of masking it.
