Objective
The objectives that the present project seeks to achieve are the realisation, characterisation and optimisation of active waveguides operating at room temperature tunable in the green-red wavelength region based on alkali fluoride films coloured by low energy electron beams with the aim of a full compatibility with integrated optics technology.
The expected results are:
- at the end of the first phase, the realisation of passive and active waveguide characterised by optical losses-gain ratio one order of magnitude lower than the presently reached;
- at the end of the project, the realisation of optically active components, i.e. tunable light emitters, lasers and amplifiers.
The work will proceed simultaneously in the realisation, characterisation, testing and optimisation of both passive and active waveguides.
If successful the project will proceed, during the second phase, towards the optimisation of the deposition parameters and to optical components design and engineering.
In the fast growing field of optoelectronics, active waveguides tunable in the green-red visible region operating at room temperature will surely find a huge application, in for instance tunable light emitters, laser and amplifiers. Up to now, it was not possible to find appropriate materials able to fulfil the compatibility requirements with the current integrated optic technologies. These shortcomings could be overcome by the use of alkali fluoride films coloured by low energy electron beams. The straightforward application of this class of materials is still limited by the their low refractive index, which introduces serious problems in the preparation of low losses-high gain waveguide. The large effort devoted to this class of materials has given promising results, attesting the feasibility of producing LiF film waveguides, which are also cost effective, more easily manufacturable and integrable with respect to bulk LiF crystals. However, for a real breakthrough of this new idea, it is still necessary to assess the possibility of increasing the current gain/loss ratio by different deposition techniques and post-evaporation treatments.
