    摘要: An optical device with variable aperture, including a deformable membrane having a central optical area, a support to which a peripheral anchoring area of said membrane is connected, a first cavity filled with a constant volume of a first transparent fluid in a determined range of wavelengths, said cavity being delimited at least in part by a first face of said membrane and a wall of the support. The optical device also includes at least one actuation device of a region of the membrane located between the peripheral anchoring area and the central optical area of the membrane, configured to bend said region of the membrane by application of electrical actuation voltage so as to displace some of the volume of the first fluid towards the center or towards the periphery of the first cavity, said displacement of fluid being intended to deform the central area of the membrane.

    摘要: A multisection digital supermode-distributed Bragg reflector (MSDS-DBR) comprising: a plurality P of digital supermode Bragg reflector (DS-DBR) grating sections arranged along a waveguide; wherein each DS-DBR grating section is configured to pass or reflect light over a given spectral region, the given spectral region being different from the spectral regions of the other DS-DBR grating sections; wherein each DS-DBR grating section comprises a plurality M of grating sub-regions, each sub-region corresponding to a spectral sub-band within the spectral region of the DS-DBR grating section, and wherein each grating sub-region includes a positive electrical contact and a negative electrical contact; said grating sub-region being configured to pass or reflect light of its spectral sub-band when an electrical bias is provided between its positive and negative electrical contacts.
