Enhancement of spectral resolution and optical rejection ratio of Brillouin optical spectral analysis using polarization pulling

Abstract: High-resolution, wide-bandwidth optical spectrum analysis is essential to the measuring and monitoring of advanced optical, millimeter-wave, and terahertz communication systems, sensing applications and device characterization. One category of high-resolution spectrum analyzers reconstructs the power spectral density of a signal under test by scanning a Brillouin gain line across its spectral extent. In this work, we enhance both the resolution and the optical rejection ratio of such Brillouin-based spectromet… Show more

“…This will lead to -2 dB insertion loss which is comparable to electronic RF filters, and is crucial to realize a filter with low noise figure and high spurious-free dynamic range (SFDR) [54,55]. Such an improvement in the insertion loss will lead to a filter technology with all-optimized properties that is essential in modern RF systems and applications.We note that the approach introduced in this paper can be generalised to schemes that use SBS for band pass filters, such as the recent demonstrations reported in [37,39,56,57], offering better extinction and more energy efficient operation in photonic integration platforms. …”

“…OSAs with a resolution of 40 fm (5 MHz) (APEX Tech.) are commercially available, while experimental approaches based on stimulated Brillouin scattering (SBS) amplification, for example, can achieve a resolution of a few tens of MHz [26,27].…”

“…SBS amplification over standard, weakly-birefringent fibers is highly polarization-dependent [41][42][43][44]. The process is associated with two orthogonal states of polarization (SOPs) of the amplified signal, corresponding to maximum and minimum gain.…”

“…The process is associated with two orthogonal states of polarization (SOPs) of the amplified signal, corresponding to maximum and minimum gain. The two states are determined by the choice of input pump SOP [42][43][44]. Let us denote the unit Jones vectors of these two SOPs at the signal input end of the fiber asê in max andê in min , and the corresponding vectors at the signal output end asê out max andê out min , respectively.…”
