It is generally recognized that two major technological breakthroughs made short-distance digital optical datacommunication commercially attractive in less than a decade: POFs (Plastic Optical Fibers) and VCSELs (Vertical-Cavity Surface-Emitting Lasers). Our project is about the latter microlasers, which, as their name says, emit light vertical to the substrate. VCSELs have been studied in detail during the past years, with a focus on the unique properties that distinguish them from or makes them superior to their edge-emitting counterparts. In this project, our goal will be to design, develop, characterize and test original VCSEL structures that obtain their enhanced functionality through a combination of fundamental physical effects and a new cavity design. Consequently, we will explore their use in the domain of smart switching, routing and photonically accelerated computing by embedding them in proof-of-principle demonstrators. Our specialty VCSELs will rely on intracavity (polarization) modulation and optical feedback through an external cavity.
