Abstract: In a nonlinear optical medium such as the gallium arsenide, two collinear incident monochromatic waves are injected to generate a monochromatic wave. The medium induces between the three waves a propagation phase-shift that has a value π if the three waves travel a coherence length in the medium and that is compensated at the value 0 modulo 2π each time that the three waves have travelled a periodic distance in the medium. In order to significantly increase the conversion efficiency, the periodic distance between two successive bounces of total internal reflection of the waves in zig-zag is strictly less than the coherence length. The high conversion efficiency on a very short material length leads to product high-power coherent optical sources particularly with wavelengths of approximately 10 μm.

Abstract: A light intensity modulator with a predefined range of modulation wavelengths (preferably a narrow range) can be adjusted by a control signal. This modulator receives a light beam and retransmits a modulated light beam in which any wavelength within the modulation range is modulated. A light intensity detector receives this modulated beam and outputs an electrical signal which is a function of the luminous intensity detected. Such a device finds particular application as a spectrophotometer.

Abstract: The oscillator comprises two resonant cavities in which a non-linear crystal (3) is situated. The incident pumping radiation Rpe follows an emitting path across the crystal, the generated signal and complementary radiation carry out numerous emitted and return paths in the cavities, hence across the crystal and are thus converted into an inverse pumping radiation on the return paths thereof. According to the invention, a device (4) is incorporated in the oscillator for reflection of a fraction of the pumping radiation equivalent to the inverse pumping radiation in the absence of the device.

Abstract: A laser made of a stack of laser diodes. The stack is inserted between two mirrors to create a laser cavity. The stack of diodes is produced by epitaxial growth of a set of semiconductor layers. The ohmic contact between two adjacent laser diodes is provided by an Esaki diode junction. The optical field of the mode created in the laser cavity is periodically cancelled at the Esaki diode junctions so as to create structures with small dimensions.

Abstract: A capacitive detector of electromagnetic waves, comprises three electron levels, wherein an internal barrier prevents a strong coupling between two levels of two neighboring wells. During an irradiation, the electrons are excited from a first level to a second level. The electrons then relax towards a third level until they relax, by tunnel effect, towards the first level. During the transition from the first level towards the third level, a dipole is created. This dipole can be detected by a detector, through the measurement of a potential difference at the terminals of the device.
