Analysis of optically pumped compact laterally coupled distributed feedback lasers with three symmetric defect regions

Hattori, Haroldo; Jagadish, Chennupati; Tan, Hark Hoe


This article analyzes compact laterally coupled distributed feedback DFB lasers with three defect regions. These devices are more flexible and smaller than conventional DFB lasers, having typical lengths between 20 and 50 m and a width less than 1 m lateral gratings are inserted in a single-mode waveguide . We optimize the defect regions to achieve an improved performance. In other words, an adequate choice of phase shifts may lead to single-mode operation, lower threshold optical...[Show more]
