摘要： The present invention relates to a vertical cavity surface emitting laser device comprising a VCSEL with a monolithically integrated photodiode. The photodiode (2) is formed of a layer sequence of a first n-doped region (6), a p-doped region (7), an intrinsic region (8) and a second n-doped region (9) of a semiconductor material. The photodiode (2) and the laser share a common electrode, which is realized as an Ohmic n-contact (10) at said first n-doped region (6). The proposed device allows less complex manufacturing, resulting in lower manufacturing costs.

摘要： The invention relates to an optical sensor module (1) for a measuring device. Said module comprises at least one optical sensor (2) including a diode laser (3) having a laser cavity for generating a measuring beam, the diode laser being attached to a substrate (12), converging means (5) (such as a lens). During measuring, such converging means (5) converges the measuring beam in an action plane and converges in the laser cavity the measuring beam radiation that has been back-scattered by an object to generate a self-mixing effect and means for measuring the self-mixing effect. Later means comprise a photo diode (4) and an associated signal processing circuitry. According to an essential aspect of the invention, that the diode laser (3) is configured to emit laser radiation of a wavelength for which the substrate (12) being attached to the diode laser (3) is transparent. This configuration leads to an essentially simple (and therefore cheap) sensor module.

摘要： A pick-up unit, an optical drive comprising such a pick-up unit, and a method of generating error-signals are described. Light reflected from an information carrier is injected into one or more VCSELs. The spatial intensity distribution of the emission from the VCSEL(s) is used for the generation of error signals in an optical pick-up unit. Alternatively, the relative timing for the switching of individual lasers of an array of VCSELs is used for the detection of error signals.

摘要： A novel class of semiconductor lasers, or 'tilted cavity lasers' includes at least one active element with an active region generating an optical gain by injection of a current and mirrors. The active element is placed into a cavity. The cavity is designed such that the optical path of the resonant optical mode is tilted with respect to both the vertical direction and the lateral plane. Thus, the feedback both in the vertical and in the lateral direction is provided for the resonant optical mode. Depending on the particular embodiment, the laser operates as both a surface emitting laser and an edge-emitting laser. Employing a tilted optical mode allows the use of substantially fewer layers in the bottom and the top interference reflectors than in conventional lasers. This preserves the necessary high reflection coefficients. Also, a wavelength-stabilized laser is realized for edge-emitters. The wavelength stabilization is due to the difference in the dispersion laws for the tilted optical modes in layers having different refractive indices.

摘要： The invention concerns an optical detector comprising a class B laser source (1) emitting a beam (3) at a first optical frequency; means (4) interacting with the beam (3) to supply a radiation (5) at modified optical frequency, the phase shift between the first frequency and the modified frequency being close to the laser relaxation frequency; means (6) for irradiating a selected zone of a medium to be studied by means of radiation at the modified frequency; means (6; 6', 12') for injecting into the laser the light sent back by the selected zone; and means (9, 14, 15, 16) for detecting the disturbance in the laser output brought about by the re-injected light.
