Figure 5: Utilizing the tailored DOS to inhibit SBS in a four-wave mixing experiment.
From: Enhancing and inhibiting stimulated Brillouin scattering in photonic integrated circuits
(a) Four-wave mixing experiment without the Bragg grating. SBS generated several idlers and, therefore, limited the maximum input power and could lead to parasitic beat signals between several SBS lines. (b) The same experiment in the presence of the grating. For the same input power no SBS was generated and therefore a single idler could be produced.
