MICROOPTICS

The focus of our research into active materials and devices for telecommunications and sensors is on the development and characterisation of optical waveguides devices.
In a series of European networking projects such as NEMO, ENOC and EFONGA, IFAC has attained a well-established set of results at both a scientific and technological level.

  • Optical microresonators: these have very high Q, and confine light within very limited modal volumes. The topics being studied at present are:
    • label-free sensors, which are extremely sensitive, for the detection of specific substances, or biological molecules for the early diagnosis of pathologies;
    • optical delay lines, for microwave transmitters.
  • Fabrication and development of optical waveguide components by means of both photolithographic techniques and thin film deposition (in class 100 and 1000 clean room), and by means of direct writing with UV light or ion-beam irradiation. An in-depth study involving special glass for the realisation of innovative devices is currently under way.
  • Microstructured optical fibres:
    • the realisation of supercontinuous sources and their application in biological microscopy (in cooperation with ISC-CNR);
    • the realisation of long-period grating for application to sensors.

A special project has recently been initiated that involves the development of waveguides in the THz band, for application to sensors and security.
