  • Light emitting device and method for making same
    Patent number: 7112829
    Abstract: A light emission device and method for producing the device. The device includes, on a substrate, a stack including an etching stop layer, a first barrier layer, an emitting layer, and a second barrier layer. The stop layer is of the same nature as the emitting layer. One may form a mirror on the stack, eliminate the substrate by etching, and form another mirror on the stop layer to obtain a micro-cavity. The device may be applied in particular to the detection of gas.

  • Bicolor infrared detector with spatial/temporal coherence
    Patent number: 6180967
    Abstract: A dual-band planar infrared detector with space-time coherence, with a stack of semiconductor layers (16, 18, 20, 21) forming first and second photodiodes. The detector has a planar structure in which each layer has a part showing on a surface (22) substantially perpendicular to the stack.
