Study of the optical properties of thin films and design of multilayer structures

Stress in optical thin films


Study of stress induced by thin films and application to high performance mirrors

Complex optical interference filters


Design and fabrication of complex optical interference filters for space applications

Phase and amplitude optical interference filters


Design and fabrication of optical interference filters with controlled phase and amplitude

In situ optical monitoring


Development of high performance in situ optical monitoring for the control of layer thicknesses during deposition


- Innovative concepts and components

Pixelated filters

Chalcogenide based optical elements


Use of photosensitivity for the fabrication of volume diffractive optical elements

Colorshift optical elements


Control of the angular dependence of the color reflected by metal dielectric structures


Finally, the RCMO team works on a wide range of other research activities associated with industrial or academic funded project :

• Broadband antireflective coating for VIS-NIR-MIR (CNES R&T project)
• Blue-enhanced silver mirrors (CNES R&T project)
• Advanced filters for space applications (Industrial projects)
• Ultra-narrowband resonant grating filters (CNES R&T project)
• Non-linearly variable filters (CNES R&T project)
