Objective
This project (RAINBOW) targets two important, closely related and fast growing markets. Firstly, high brightness outdoor lighting as used in large outdoor displays, traffic signals, automobile lighting, etc... and secondly, the market of high density optical disk storage as used in multimedia environments. To attack these areas the consortium intends to develop the first complete European Al Ga In N materials base, culminating in the mass production technology of Ultra High Brightness Light Emitting Diodes (UHB LED) in various colours and in the fabrication of blue laser nitride. The present consortium, including major manufacturers of electronic components (U1), laser diodes (U2), growth reactors, (M1), starting chemicals (M2) together with experts in device design (R1), reactor design (R3), materials characterisation (R2) and nitride material process (R4) can put Europe beyond our Japanese and American competitors and request the commissions support to achieve this aim. Through R4 a collaborative will be created with LTR LAQUANI project, to our knowledge the only fundamental research project running. The final scope being the mass production of LED's and lasers, the following objectives will be achieved in the framework of this project:
1) Realization of optoelectronic device demonstrators including:UHB LED's prototype emitting in the range 400nm to 590nm with luminous intensity of 4cd
laser diode samples operating at a wavelength of around 400nm with CW output power (Pout) of 5mW at room temperature.
2) Development of device processing technology for Ga Al In N based alloys, applicable to both multicoloured UHB LED's and blue laser diodes.
3) Development of material fabrication process (MOVPE growth) for the Al Ga In N multilayer structures applicable to both multicoloured UHB LED's and blue laser diodes.
4) Development of optimum group III and nitrogen precursors to allow the epitaxial deposition of group III nitrides with reduced pre reaction and reduced V/III ratios (from the present 1000:1 to below 100:1).
Almost all the technological development of a UHB LED is identical to that required for a laser where a beam of stimulated emission is generated by the addition of two parallel reflecting faces. After completion of the proposed three years RTD project, it is expected that an additional six months will be required to optimize LED and laser prototypes. After that, six more months will be needed to introduce the multicoloured LED prototype to the market place. The marketing of the developed epitaxial process will begin three months after the completion of the project.
