High brightness laser diode technology is a key enabling technology for the information society of to-morrow, especially in the fields of health-care, telecommunication, environment and security. The development and achievements of the information society relies on a smart use of the information for applications such as imagery or telecommunications. The electron and the photon are the two main information carriers, the latter having taken an increased role since the end of the seventies, when engineers demonstrated the efficiency of optical fibre transmission. Since then, the demand for high brightness sources has increased continuously. Laser diodes already offer extraordinary compactness at a reasonable cost and now play a central role in telecommunications. However, their brightness still needs to be improved to spread their large-scale uptake across the Information Society; the main challenge is to couple more light power in smaller diameter fibres.
The WWW.BRIGHT.EU consortium proposes a long-term vision aiming at pushing the limits of the current laser diode technology towards higher brightness, and at demonstrating applications such as:
- Medical imagery for cancer therapy
- Amplifiers for telecommunication networks
The approach consists of mobilising the expertise of the main European actors of the laser diode core technology, and coupling it with highly innovative optical technologies e.g. smart cavity concepts for higher efficiency and tuneability. Industrialisation constraints will be widely addressed through packaging and reliability studies.
This project is intended to be the first phase of 24 months a more long-term and ambitious project; this first phase will allow on one hand the full assessment of a few targeted applications corresponding to strong market needs such as photodynamic therapy, on the other hand the development of core technologies for which the applications would be fully assessed in the second phase.
