    摘要: The field of the invention is that of semiconductor devices used for the amplification or for the phase modulation of optical signals. These devices are known by the generic names SOA (semiconductor optical amplifier) and DPSK (differential phase shift keying) modulators. The main drawbacks of this type of device are that it is, on the one hand, difficult to obtain a constant gain, and, on the other hand, it is difficult for the optical signal to be independently amplitude-modulated and phase-modulated. The device according to the invention does not have these drawbacks. It relies essentially on three principles: the active zone of the device has a quantum dot structure, the atoms of said structure possessing a first energy transition state called the ground state and a second energy transition state called the excited state; the active zone is placed in a structured resonant cavity in order to resonate at a first wavelength corresponding to the ground state; and the current flowing through the active zone is greater than the saturation current of the ground state so as to allow oscillation at a second wavelength corresponding to the excited state.

    摘要: The field of the invention is that of the semiconductor optical devices used in particular for fibre-optic telecommunications. To function efficiently, a certain number of semiconductor devices require the use of light polarized in a given polarization state. When knowledge of the polarization the state is lost, the optical element according to the invention makes it possible to polarize the light again in a known polarization state. By using two of these elements in combination with a coupler, it is possible to produce a device which fulfils the same function as a polarization splitter. This optical assembly delivers two output signals whose polarization states are the projections of the initial polarization onto two orthogonal axes. The main advantage of these devices is that they are produced using polarization rotators based on photonic crystals, and they can consequently be integrated easily into semiconductor devices, which the use of discrete polarizers does not allow.

    摘要: The field of the invention is that of optical devices comprising an integrated semi-conductor laser and an integrated optical isolator. These devices are used mainly in the field of digital telecommunications. More particularly, the invention applies to so-called absorption isolators whose complex index is non-reciprocal and depends on the direction of propagation of the light. Generally, integrated optical isolators of this type fulfill two functions. On the one hand, they comprise a magneto-optical layer ensuring the non-reciprocal effect and on the other hand an active zone ensuring the amplification of the laser beam, the injection of the charge carriers into the active zone being ensured by an electrical contact layer. The invention proposes, so as to limit the disturbing effects of the contact layer on the propagation of the laser beam, that the contact layer be eliminated above the active zone and that the injection of the charge carriers be ensured via the lateral faces and the edges of the upper face of the active zone.
