Objective Future high efficiency displays and optical interconnect architectures will require planar, addressable, high brightness and directional light emitting devices. SMILES aims to understand and develop conceptually new high brightness light emitters, emitting in the visible and near infrared, based on enhanced spontaneous emission in resonant III-V and II-VI microcavities and in composite photonic bangap structures. These devices will be probed as a basis for new room temperature ultrahigh speed excitonic LEDs and lasers, and also as a viable route to II-VI solid state light emitters.APPROACH AND METHODS The association of partners and the complementary division of tasks has been chosen to bring together a sufficiently broad range of expertise to evaluate quantitatively microcavity effects in light emission. Materials growth will be carried out in EPFL, Lausanne (MBE of III-V's) and TUT, Tampere (MBE II-VIs), with GENT providing MOCVD of overlayers or mirrors whenever required. Characterisation and elucidation of microcavity physics is to be carried out in EPFL (III-V studies, emission and directionality of planar and 3D cavities), Ecole Polytechnique Palaiseau (II-VI studies, strong coupling of evaluation of II-VIs), and in TCD Dublin (transient emission and emission mechanisms of III-VIs and II-VIs). Assessment of new light emitters device potential will be carried out in EPFL (photopumped III-V's) and TCD (photopumped II-VIs). TUT, IMEC and EPFL (electrically injected III-Vs and II-VIs) will respectively explore the output characteristics of emitters, the efficiently of emission and the directionality of that emission. POTENTIAL The proposed programme aims at exploring new concepts in light emitters with improved performance. The output of this research will enhance the competitiveness of the European IT industry. Arrays of high brightness, high speed and efficient near-IR LEDs and lasers are ideal for optical interconnects between computers, while high efficiency grey-scale LED will find immediate application as analogue transmitters for CATV or HDTV signals and for printers. Additionally, high brightness visible sources based on wide bandgap II-VI materials are desirable for display technologies and optical data storage.
