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.
