Today, it covers a wide wavelength emission range (from the blue-green band up to the infrared) that enables the usage of these components in various application fields, not only in the short distance digital communications (LAN, Avionic network (Ly et al, 2008), ...) but also in consumer applications (laser printers, laser mice, display systems, etc.). All these applications can be made possible thanks to:…”
