Zepren

Patented Brillouin high-resolution spectroscopy

Based on revolutionary all-optical patented technology, Zepren Solutions produces the most advanced High Resolution Optical Spectrum Analyzer products.The principle behind BOSA performance is stimulated Brillouin scattering (SBS), a non-linear optical effect produced by narrow-linewidth high-power light propagating through an optical fiber that causes a very narrow filtering effect. By pumping SBS with an external cavity tunable laser source (TLS), the filter is swept along the spectral region of interest, giving the high-resolution optical spectrum.
