摘要： The invention relates to a frequency converter comprising a guide and a non-linear medium (NLM) in which the condition of phase matching between non-linear polarization and created waves is satisfied locally. The object of the invention resides in an additional layer C lying on the medium (NLM), the refractive index of which is such that it increases the conversion yield, for conversion of the incident waves to the waves created within the guide. This layer may be a symmetrization layer whose index is close to the index of the medium (NLM). The conversion yield may be further increased by means of an intermediate layer C.sub.ex, which lies between the layer C and the medium (NLM) and the index of which is close to that of the guide.

摘要： The invention pertains to an electromagnetic wave modulator comprising a quantum well semiconductor structure having two adjacent wells, the coupling of which is modified under the effect of an electrical field by the use of the phenomenon of anti-crossing of resonating levels. With this type of modulator, it is possible to attain 20% of modulation (as in the prior art) but with heightened sensitivity to the electrical field and a very short response time.

The energy corresponding to a first permitted level is lower than the potential energy at the bottom of a conduction band of both of the materials used to make the second and third layers and the energy of the second level is between the potential energy at the bottom of a conduction band of both materials of the second and third layers and the potential energy of the bottom of the conduction band of the materials of the fourth and fifth layers. The first permitted level of energy of the quantum well is populated with electrons and an electric field is applied perpendicular to the plane of the structure.

摘要： A frequency shifter to shift the frequency of a guided wave in the medium infrared range comprises:an optical guide, formed by semiconducting materials, on the surface of which a diffraction grating is created by carriers photo-induced by a periodic illumination.standard optic means projecting, on the surface of the guide, two wave beams having different frequencies in the near infrared or visible range, to produce, by interference, a periodic illumination of the surface of the guide. This illumination induces photocarriers constituting a diffraction grating which is in translational motion at constant speed. This motion shifts the frequency of the diffracted wave by Doppler effect.

摘要： The invention relates to a modulation ratio amplification device, particularly for amplification at UHF. This device comprises means for making two optical waves, which are of the same amplitude but offset in frequency, interfere. These means may be a frequency converter, coupled to a continuous phase shifter; they may also involve two phase shifters: one continuous, the other varying sinusoidally over time. This type of device makes it possible greatly to amplify the desired modulation ratio, using an optical amplifier, given that the continuous background of the optical signal is suppressed.

摘要： Disclosed is a compact and coherent optical source using a laser that emits an incident wave at a wavelength .lambda.o.sub.i, a non-linear medium (NLM) in which the phase matching condition is verified at the wavelength .lambda.o.sub.a belonging to the set of .lambda.o.sub.i values. This optical source furthermore has two dichroic mirrors M1 and M2 at the points of entry into and exit from the non-linear medium that are highly transparent at the wavelengths .lambda.o.sub.i and highly reflective at the wavelengths .lambda.o.sub.i /2. Such a configuration advantageously enables the locking of the emission of the laser into the wavelength .lambda.o.sub.a, the recovery of a light wave at .lambda.o.sub.a /2 and, thus, the amplification of the emitted power at .lambda.o.sub.a /2. Application to blue sources.
