Interdepartment projects gather researchers and engineers from the different FEMTO-ST departments to work on multidisciplinary objectives.
Exploration of periodic micro and nanostructures which simultaneously show photonic and phononic band gaps. Application to optical telecommunications (modulators, suppression of the Brillouin effect stimulated in optical fibres).
Exploration of nanosensors using electromagnetic interactions (between RF and Optics) in near-field for micro-CEM, biotechnologies and high-resolution instrumentation applications.
integration of microscopes with local probes on chips: study of optical nano reading and writing systems which comprise micro contilevers fit with VCSEL diode laser (vertical-cavity surface-emitting lasers) and assembled on MEMS systems which perform spatial scanning functions (optical version of the IBM “Millipede”).
Atomic micro clocks on the order of one cubic centimetre (see DARPA competitive project). Study of appropriate laser micro-sources, physical study on interaction with atomic vapour in micro-volumes. Study of the key microfabrication technologies.
Elaboration of a temperature probe with a metrologic quality (for “time-frequency” applications) using a quartz crystal sensor and an ASIC circuit specially elaborated at FEMTO-ST in order to be integrated with the sensor and to give it all its precision.
Study of distributed systems for the active control of mechanical structures (acoustic control, vibrations, streamline flows). Use of mechanically active materials (AMF, piezo) or MEMS. These works also deal with the study of command electronic components (the command strategy will be studied via external collaborations).
