Abstract

The design and experimental characterization of sidewall-etched gratings in III-V material fabricated with a post-growth technique are presented. The successful demonstration of an array of sidewall-etched distributed feedback lasers shows that this technology allows for a very accurate control of the wavelength spacing and a sidemode suppression ratio up to 60 dB.
