Abstract: An optoelectronic device includes at least one pixel, each pixel comprising an optical resonator comprising a photodetecting structure confined between a reflective metal layer and a second reflective metal layer; and a readout integrated circuit arranged on a substrate and comprising at least one buried readout electrode dedicated to the pixel and at least one metal or dielectric outer layer. The assembly comprising at least the reflective metal layer and the outer layer of the readout integrated circuit is called a planar assembly structure. The first metal layer is connected to the readout electrode by way of a metal via passing through the optical resonator structure and the planar assembly structure. The metal via is electrically isolated from the photodetecting structure and from the planar assembly structure.

Abstract: An optical detector that is sensitive in at least two infrared wavelength ranges: first spectral band and second spectral band; and having a set of pixels, comprising: an absorbent structure disposed on a lower face of a substrate and comprising a stack of at least one absorbent layer made of semi-conductor material; the detector further comprising a plurality of dielectric resonators on the upper surface of said substrate forming an upper surface metasurface, the metasurface configured to diffuse, deflect and focus in the pixels of the detector in a resonant manner, when illuminated by the incident light, a first beam having at least one first wavelength included in the first spectral band and a second beam having at least one second wavelength included in the second band, the metasurface also being configured so that said first and second beams are focused on different pixels of the detector.

Abstract: An optoelectronic device includes at least one pixel comprising: a plurality of optical resonators, each optical resonator comprising a photodetecting structure confined between a first reflective metal layer and a second metal layer; and a connection microstructure that is arranged on a support made of dielectric material and is configured to electrically interconnect the second metal layers of the optical resonators belonging to the same pixel; and a readout integrated circuit arranged on a substrate and assembled with the pixel; the readout circuit comprising a buried readout electrode associated with the pixel and a metal or dielectric outer layer. The assembly comprising at least the first metal layer and the outer layer of the readout integrated circuit is called a planar assembly structure. The second metal layers of the resonators of a pixel are connected to the associated readout electrode by way of a metal via connected to the connection microstructure and passing through the support.

Abstract: A free space optical FSO space data transmission system includes a first ground or aeronautical optical terminal, a second optical terminal housed on board a satellite, and a relay platform. The relay platform is configured so as to move at an altitude higher than that of clouds and atmospheric turbulence, so as to receive the data transmitted by the first terminal in the MWIR/LWIR domain of long wave infrared LWIR wavelengths and/or medium wave infrared MWIR wavelengths, and retransmit the received data to the second terminal in the domain of short wave infrared SWIR wavelengths, and/or receive the data transmitted by the second terminal in the domain of short wave infrared SWIR wavelengths, and retransmit the received data to the first terminal in the MWIR/LWIR domain of long wave infrared LWIR wavelengths and/or medium wave infrared MWIR wavelengths.
