Abstract: A photonic gas sensor and a method for producing a photonic gas sensor are disclosed. In an embodiment a photonic gas sensor includes a component housing with at least one cavity, a radiation-emitting semiconductor chip arranged in the cavity and configured to transmit electromagnetic radiation in a first wavelength range, a radiation-detecting semiconductor chip arranged in the cavity and configured to detect electromagnetic radiation in a second wavelength range and an active sensor element having a fluorescent dye configured to emit electromagnetic radiation in the second wavelength range upon being excited by electromagnetic radiation in the first wavelength range, wherein an intensity of the emitted electromagnetic radiation in the second wavelength range changes reversibly in presence of a gas to be detected.

Abstract: A semiconductor light source configured for a spectrometer may include at least one multipixel chip, at least one color setting component disposed optically downstream of at least one of emission region, and a drive unit. The color setting component may be configured for altering a spectral emission behavior of assigned emission regions. The drive unit may be configured to operate a plurality of mutually independently drivable emission regions successively, such that during operation thereof at least three spectrally narrowband individual spectra are emitted successively by the plurality of mutually independently drivable emission regions together with the associated color setting component from which individual spectra a total spectrum emitted by the semiconductor light source is constituted.
