BOSA is the most advanced and versatile
High Resolution Optical Spectrum Analyzer
in the market. Thanks to our unique optical
filtering and full spurious free dynamic range
the BOSA achieves reliable measurements
avoiding artifacts and undesired effects on
your measurements.
BOSA’s unique combination of high-resolution
and high dynamic-range brings a new range
of measurement possibilities to the optical
domain. BOSA reveals the optical spectra of
the signals with a detail and precision that
enables direct measurement of performance
parameters for lasers and modulated signals.

Technology
Aragon Photonics all-optical patented
technology use the stimulated Brillouin
scattering (SBS) as a non-linear optical effect
that causes a very narrow filtering effect.
By pumping the 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. SBS
gain enhances the dynamic range of the
measurement compared to passive filtering,
and the threshold imposed by SBS eliminates
all the spurious effects of the local oscillator
sidemodes and lineshape that produce
measurement artifacts in heterodyne OSAs,
giving the highest spurious-free dynamic
range measurement available in market.
Based on our core SBS technology we have also
developed unique measurements solutions
for the characterization of the polarization
and phase of the optical spectrum, providing
the most complete characterization of an
optical signal available in any HR-OSA.
