Objective
Research objectives and content
The research project is aimed at the development of spatially selective laser intermixing techniques . suitable for the fabrication of photonic integrated circuits (PlC's) on InP/lnGaAsP based quantum well (QW) laser structures. The basic fabrication technology for semiconductor lasers will also be addressed and developed. In order to achieve high spatial resolution, the following laser direct writing methods will be used: (a) irradiation with a focused CW Nd:YAG gaussian laser beam (spot size down to 10 mm) with fast scanning in selected areas by laser direct writing; (b) irradiation with two Nd:YAG laser beams, one large diameter CW beam to act as a thermal bias for the sample and the other pulsed and focused beam to locally generate point defects inducing interdiffusion in selected areas. The detailed research program, to be completed during the 12 months period of the return grant, would be the following 1) ridge QW lasers fabrication and testing. 2) experimental study using the methods (a) and (b) and fabrication of extended cavity ridge lasers with relevant characterisation. 3) post fabrication wavelength trimmirig of a monolithic array of 4 Fabry-Perot ridge lasers for application in WDM optical communication systems. 4) multilayer dielectric thin films mirrors or antireflection coating deposition on semiconductor laser facets with in situ thickness monitoring by reflectometry. The proposed research project will link together the experience on QW intermixing gained by the candidate, during the 24 months period of the category 30 grant (Human capital and Mobility Program) spent in the Optoelectronics Research Group, Department of Electronics and Electrical Engineering, Glasgow University, with the expertise in laser direct writing, micropositioning systems and their control, thin films deposition and microfabrication already present in the home institution (Dipartimento di Ingegneria Elettrica, University of Palermo, Italy), in view of a strong collaboration in the near future. Links with industry t industrial relevance (22)
The home research group (Laboratorio Tecnologie Optoelettroniche) has just received a grant from the Italian National Research Council (CNR) for research in the field of III-V semiconductor optoelectronics. This will allow the acquisition of more specialised equipment needed for the proposed research activity. It also indicates a special care of the Italian CNR for a subject which is gaining a growing industrial interest in Italy and is rapidly movung from the research phase to practical applications.
