Abstract
In this letter, we present the study of the small signal modulation response of a monolithic twin ridge laterally coupled diode lasers. Such structures have been extensively theoretically studied for their promising characteristics as high-speed optical sources for optical communications, and in this work we demonstrate the increase of the small signal bandwidth beyond the relaxation oscillation frequency with the appearance of a second peak in the small signal response due to the laterally mode locking of these two emitters.
