Abstract

In an embodiment an apparatus includes at least one optoelectronic laser configured to provide excitation radiation to a sample, the excitation radiation being generated by an electric current flowing through the at least one optoelectronic laser, a transistor configured to modulate the electric current flowing through the at least one optoelectronic laser in order to switch on and off generation of the excitation radiation and a spectrometer configured to analyze Raman light scattered from the sample in response to exposing the sample to the excitation radiation, wherein the Raman light includes one or more spectral components, wherein the spectrometer includes a diffraction element configured to split the Raman light into the spectral components, and wherein the diffraction element includes at least a photonic crystal or a plasmonic Fabry Perot filter.
