“…3(b), showing a 0.22-pm FWHM linewidth. The measurement has been performed utilizing a recently published technique which is based on the amplification of the laser signal by means of the Brillouin back-scattering peak of a tunable laser [13]. The theoretical spectral resolution of this technique is of 0.08 pm.…”

“…Optical filters are essential in a wide range of applications, including optical communications [1], spectroscopy [2,3], electronics [4] and optical sensors [5~9]. Especially, high resolution optical spectroscopy of high performance optical sensors has always attracted considerable interest and characters of optical spectrum analysis (OSA) such as resolution, dynamic range and measurable range highly depend on optical filters.…”

“…The gain spectrum bandwidth of SBS is several MHz and its gain spectrum can be swept with a tunable laser. This technique achieved a spectral resolution of 80 fm (~10 MHz) and a swept range of 40 nm in an 11.5-km length dispersion-shifted fiber [2]. Later, superposition of three Brillouin lines and vector attributes of SBS amplification in standard, weakly birefringence fibers, were utilized to improve its spectral resolution to 3 MHz [12].…”

To achieve a narrow bandwidth optical filter with a wide swept range for new generation optical spectrum analysis (OSA) of high performance optical sensors, an optoelectronic equivalent narrowband filter (OENF) is investigated and a swept optical filter with bandwidth of several MHz and swept range of several ten nanometers is built using electric filters and a swept laser as local oscillator (LO). The principle of OENF is introduced and analysis of OENF system is presented. Two electric filters are optimized to be RBW filters for high and medium spectral resolution application. Both simulations and experiments are conducted to verify OENF principle and results show that power uncertainty is less than 1.2% and spectral resolution can reach 6 MHz. Then, a real-time wavelength calibration system consisting of HCN gas cell and Fabry-Pérot etalon is proposed to guarantee a wavelength accuracy of ±0.4 pm at C-band and to reduce the influence of phase noise and nonlinear velocity of swept LO. Finally, experiments on OSA of actual spectra of various optical sensors using OENF system are conducted. Experimental results indicate that OENF system has an excellent capacity in analysis of fine spectrum structures.

“…Optical fibers with the ability of confining light in a small mode area and a long distance have been successfully used to enhance and study the SBS processes. SBS has thus been demonstrated in traditional fibers, [2][3][4][5][6][7][8][9][10][11][12] photonics crystal fibers [13] and sub-wavelength microfibers [14] . On-chip optical waveguides are also very promising platforms for integrated solutions to harvest the SBS effect [15][16][17] .…”

Optical whispering gallery mode resonators are important platforms to enhance and study various nonlinear frequency conversion processes. Stimulated Brillouin scattering is one of the strongest nonlinear effects, and can be successfully investigated using these platforms. In this article, we study the phenomenon of stimulated Brillouin scattering using a crystalline disk resonator. A fast scanning ringdown spectroscopy technique is used to characterize the optical modes featuring quality factors of the order of one billion at telecom wavelengths. The mW scale threshold power in a centimeter disk resonator is observed and found to be strongly dependent on the gap between the resonator and the prism coupler.
