Abstract
We describe the effects of additional feedback in external cavity semiconductor lasers, which are sensitive to feedback phase. It is shown that additional feedback with favorable phase can serve to enhance mode selectivity. The optimum feedback conditions to maximize the system immunity against unwanted additional feedback with unfavorable phase have also been determined.
