A part of MOSAIC research activities focuses on miniaturization of complex optical systems. For this purpose, we associate silicon / glass microfabrication processes, MEMS and micro-optics, in order to develop novel building blocks and architectures.
On the first hand, this is applied to the development of optical microscopes, in particular OCT (optical coherence tomography) integrated systems, whether for endoscopic probes or for large field-of-view investigation when several interferometers are arranged in array.
On the other hand, we aim at developing atomic systems, especially miniaturized atomic clocks based on alkali vapor.
DOCT-VCSEL
DOCT-VCSEL aims at demonstrating and implementing a new generation of MEMS-VCSEL swept-sources emitting at 850 nm and their integration in a highly miniaturized OCT system for skin pathologies detection.
Cutaneous cancer is currently the most commonly diagnosed type of cancers and its early diagnosis increases the chances of successful treatment...

PULSACION
Chip-scale atomic clocks (CSACs) provide unprecedented frequency stability within volumes down to a few cubic centimeters and power consumptions as low as 100 mW. In this framework, the ANR project PULSACION aims at providing novel solutions in order to improve the long-term frequency stability of miniature atomic clocks based on coherent population trapping (CPT)...
