摘要： The present invention relates to a VCSEL which at least comprises on a substrate (1) a first and a second mirror stack (2, 3) forming a resonant cavity, an active region (4) sandwiched between said first and said second mirror stack (2, 3), and a current aperture layer (5) defining a current confinement aperture (6). The current confinement aperture (6) extends at least partly around a central electrically insulating area (7) of said current aperture layer (5). The proposed VCSEL avoids or at least reduces the risk of current crowding, lowers the thermal resistance and enables the generation of ring-shaped beam profiles in the far field. A central hole ( 9 ) may be etched in the second mirror stack (3) to allow for wet oxidation of the current aperture layer (5) from two sides resulting in an annular current confinement aperture (6).

摘要： The present invention relates to an optical clement for VECSELs or VECSEL arrays. The optical element is formed of a substrate (200) which is transparent at least in a wavelength region of optical radiation. A first interface of the- substrate (200) comprises one or several curved regions forming part of an optical lens or of an array of optical lenses (220) integrated in the substrate (200). The substrate (200) further comprises one or several optical mirrors (210) formed on a second interface of the substrate (200) opposing the first interface or embedded in the substrate (200). The optical mirrors (210) are arranged and designed to back reflect a fraction of optical radiation incident on the first or second interface. The optical mirrors (210) are flat mirrors or curved mirrors having a radius of curvature different from the radius of curvature of the curved region (220). The optical element allows the fabrication of a VECSEL or VECSEL array having a high brightness without the requirement of additional adjustments during fabrication. The VECSEL are arranged at a distance (L) to the optical mirrors (210) and this equals the length of the external cavity. The ROC of the optical lens may be chosen to ROC = L/2 and for the optical mirror ROC > L. The cavity length may be adjusted by a monolithic spacer (120)

摘要： The present invention relates to a laser device comprising at least one large area VCSEL (101) and at least one optical feedback element (201, 301) providing an angular-selective feedback for laser radiation emitted from the laser. The angular-selective feedback is higher for at least one portion of laser radiation emitted at angles θ > 0 to the optical axis (601) of the laser than for laser radiation emitted on said optical axis (601). The invention also refers to a method of stabilizing a laser emission of a large area VCSEL in a desired angular distribution (501, 502). With the proposed device and method, the intensity distribution of a large area VCSEL can be stabilized in a desired shape, for example a ring shape.

摘要： The present invention relates to a semiconductor laser device, in particular a V(E)CSEL,using current-limiting apertures to tailor the gain profile of the laser. The laser comprises a layer stack sandwiched between a n-contact (7) and a p-contact (2), said layer stack at least containing an active region (5) and a p-doped semiconductor mirror (1) arranged on a p-doped side of the layer stack.

摘要： The invention relates to a lighting apparatus (1) comprising an array (2) of light sources (3) emitting emission cones (4) with edges (5) which intersect in an intersection plane and a lens unit (7) for homogenizing the intensity distribution in the far field. The array of the light sources and the lens unit are arranged such that i) the emission cones traverse the lens unit and ii) the distance ( s ) between the array of the light sources and the lens unit deviates from the sum of or the difference between a) the focal length f of the lens unit and b) the distance t between the intersection plane and the array (2) of the light sources (3) by 20 percent or less. This configuration leads to an intermixture of the emission cones in the far field such that the intensity distribution in the far field is substantially homogeneous.
