    Abstract: A method for removing the growth substrate of a circuit of electromagnetic radiation detection, especially in the infrared or visible range, said detection circuit including a layer of detection of said radiation made of Hg(1-x)CdxTe obtained by liquid or vapor phase epitaxy or by molecular beam epitaxy, said detection circuit being hybridized on a read circuit. The method includes submitting the growth substrate to a mechanical or chem.-mech. polishing step or to a chemical etch step to decrease its thickness, all the way to an interface area between the material of the detection circuit and the growth substrate; and submitting the interface thus obtained to an iodine treatment.

    Abstract: The invention relates to wavelength-selective and tunable optical filters for transmitting the light in a narrow optical spectral band, centered around an adjustable wavelength, and for blocking the transmission of wavelengths lying outside of this band.In a micromachined monolithic structure containing the optical filter proper, the component comprises a low-absorption light detection element used for slaving the tuning control of the filter to a wavelength received by the filter, this element transmitting the majority of the radiation at this wavelength. The filter is a Fabry-Pérot interferometric filter, the cavity (C) of which is tuned to a value that maximizes the power detected by the light detection element. The filter is preferably based on layers of indium phosphide and air gaps. The detection element preferably comprises a layer of gallium-indium arsenide 74 suitable for detection of the intended wavelength band.
