Abstract

Optical spectrum analyzers (OSAs) with high spectral resolution are of significant interest in the fields of sensing, spectroscopy, and communication. However, as recent researches have been no longer satisfied with the spectral resolution of the current available OSAs, new methods are needed urgently. In this paper, we experimentally demonstrate an OSA combining the Rayleigh backward scattering (RBS) and the heterodyne interferometry. As the interferometry configuration downshifts the backward scatterings from the optical frequency band to an electronically tractable frequency range, the responses raised by the concomitant stimulated Brillouin scattering (SBS) could be filtered out by an electrical low-pass filter. Benefiting from this combination, the proposed Rayleigh-assisted coherent optical spectrum analyzer (RCOSA) could achieve a spectral resolution of10 kHz(0.08fm).
