Research project integrates laser directly on silicon with a modulator

IRT Nanoelec, an R+D consortium focused on information and communication technologies using micro- and nanoelectronics, today announced the first co-integration of a III-V/silicon laser and silicon Mach Zehnder modulator demonstrating 25 Gbps transmission on a single channel. This transmission rate usually is achieved using an external source, over a 10 km single-mode fiber.
