Abstract: The invention relates to an apparatus and a method for evaluating spectral properties of a measurement object. It comprises a plurality of light emission units, each emitting light with a predetermined emission spectrum and having a respective output configured for emitting the light with the predetermined emission spectrum onto the measurement object, an optical spectrograph having an input port adapted to receive light from the measurement object and a diffraction unit adapted to distribute different wavelengths of the received light to different output ports comprising the optical detectors, wherein the diffraction unit is adapted to distribute said received light to the respective output ports such that the lights in the respective output port have different wavelengths at different diffraction orders; a signal identification unit adapted to identify which of the light emission units contribute to the respective light in the respective output ports.

Abstract: A resonator structure containing an active layer is subdivided into at least two sections in which mode spacings differ from one another by 7 to 10 percent on account of different length dimensions or as a result of grating structures provided therefor. Photonic crystals are integrated as longitudinal and, if appropriate, as lateral boundaries of the resonator structure. Variation of the currents in the sections enables the laser to be tuned in a wide wavelength range.

Abstract: In the method and the arrangement, a ratio (p2/P3)—which is independent of the total optical power of the laser (1)—between a power (p2) essentially containing only the wavelength (&lgr;) to be stabilized, which power is filtered out from a portion (P2) of the total power (P0), and an additional portion (P3) is measured and compared to a desired value (S0), and, given a deviation from the desired value (S0), the temperature of the laser (1) is controlled to the desired value (S0).
