Abstract

Coherent anti-Stokes Raman scattering (CARS) offers label-free detection with chemical selectivity. In order to achieve spectral and therefore chemical resolution two synchronized narrowband pulses have to be provided by an appropriate light source. The often used complex laser systems as well as the more recently introduced all-fiber approaches based on seeded four-wave mixing (FWM) [1,2] all lack the compatibility with integrated photonics.
