摘要： A semiconductor device includes an active layer configured to radiate light, a light reflecting facet positioned on a first side of the active layer, a light emitting facet positioned on a second side of the active layer thereby forming a resonant cavity between the light reflecting facet and the light emitting facet, and a partial diffraction grating having a predetermined length and positioned on a light reflecting side of the resonator. The predetermined length of the partial diffraction grating is selected such that the semiconductor device emits a light beam having a plurality of longitudinal modes within a predetermined spectral width of an oscillation wavelength spectrum of the semiconductor device. The predetermined length of the partial diffraction grating may be set in relation to a length of the resonant cavity, or in relation to a coupling coefficient of the diffraction grating. The semiconductor device may also include another partial diffraction grating positioned on the light emitting side of the laser device.

摘要： The invention concerns an optoelectronic system comprising at least three sections (A, B, C) corresponding to specific respective functions and having different forbidden band energy levels respectively. The invention is characterised in that said three sections consist of at least two layers (20, 30) superposed by epitaxy, the upper layer (30) being etched to define said sections in the form of two separated end sections (A, C) delimited in the upper layer (30) on either side of an intermediate section (B) defined in the lower layer (20), and to enable a coupling between the intermediate section (B) and each of the end sections (A, C) enclosing it, by evanescent field coupling, the energy level of the forbidden bands of at least one of the sections defined in the upper layer (30) being controlled by carrier injection.

摘要： The thermo-optic behavior of an optical path over a range of temperatures ΔT is controlled by determining a figure-of-merit (FOM) for the optical path and including in the path a body of crystalline material that enables the conditions specified by the FOM to be satisfied. The crystalline material is highly transparent at a wavelength λ of radiation propagating in the path, and it has a coefficient of thermal expansion (CTE) and a refractive index n such that the CTE and dn/dT are mutually adapted to satisfy the FOM over the range ΔT. In one embodiment, the CTE and dn/dT of an etalon compensate one another so as to perform frequency discrimination that is essentially temperature insensitive over the range ΔT. In a preferred embodiment of the optical etalon the crystalline material comprises LiCaAlF 6 .

摘要： Un générateur (1) d'impulsions optiques à réflecteur de Bragg distribué est caractérisé en ce que le réflecteur est un réseau (40) réflecteur de Bragg échantillonné, ayant plusieurs pics de réflexion, chaque pic correspondant à une valeur de fréquence optique de réflexion, la différence entre des valeurs consécutives de fréquences de réflexion étant égale à un multiple entier P de la différence entre des valeurs consécutives de fréquences de modes pour lesquelles une cavité optique formée entre une face arrière (13') d'une couche active et un point de réflexion du réflecteur (40) est résonante.
On obtient ainsi des impulsions très courtes avec une faible gigue temporelle.

摘要： An optical transmitter providing the benefits of both filter-locked and wavelength-locked lasers is disclosed by modifying an external cavity (32) for the integration of an optical modulator (14). The external cavity (32) provides a round-trip path for light travel. A substrate (24) is connected to the external cavity (32) where at least one gain element (16) and the optical modulator (14) are integral with the substrate (24). A partial reflector (40) is also integral with the substrate (24) and couples the at least one gain element (16) with the optical modulator (14).
