“…Supercontinuum sources based in PCFs can be applied in optical coherence tomography [22] and in spectroscopy [23]. PCFs for sensing applications have also been widely demonstrated [24], in order to measure a variety of parameters: curvature [25]; strain/displacement [26]; electric field [27] as well as magnetic field [28]; pressure [29]; temperature [30]; torsion [31] and transversal load [32]; refractive index [33]; vibration [34]; gases [35]; DNA [36]; proteins [37]; rhodamine [38]; salinity [39]; pH [40] and humidity [41].…”

A review on all-fiber lasers based on photonic crystal fibers is presented. Photonic crystal fibers present improved features beyond what conventional optical fibers can offer. Due to their geometric versatility, photonic crystal fibers can present special properties and abilities which can lead to enhanced lasing structures. A brief description of photonic crystal fibers and fiber laser's properties is presented. All-fiber laser structures developed using photonic crystal fibers are described and divided in two groups, depending on the cavity topology: ring cavity fiber lasers and linear cavity fiber lasers. All-fiber lasers applications in the photonic crystal fiber related sensing field are described.

“…The micro-structured optical fibers (MOFs) [4], also called photonic crystal fibers (PCFs) when the cladding air holes are arranged periodically, have been widely used in fiber lasers [5], sensing [6] and the SC generation, etc. MOFs possess unique properties to control nonlinearity and dispersion because the transversal design can influence the modal confinement and waveguide dispersion [7].…”

A microstructured optical fiber (MOF) structure with longitudinal dispersion variation is theoretically investigated for broad, coherent supercontinuum (SC) generation in the infrared (IR) region. The MOF possesses anomalous dispersion at 1550 nm but changes its dispersion to normal dispersion by a tapering process. The inline dispersion controlled structure provides a linear chirp and the subsequent pulse compression without additional components. The compressed pulse then seamlessly enters a short normal dispersion section for the coherent SC generation. Our simulation suggests that the inline structure can be as short as around 11.6 cm to realize the pulse compression and the SC generation. In particular, only 0.5-cm-long final normal dispersion section is required for the coherent SC generation, hence avoiding high background loss particularly in the spectral region above 2 m, where silica glass absorption becomes considerably high. In the structure, the peak power of a pulse is enhanced by 14 times in the compression process, and the corresponding generated SC spectrum has a bandwidth of 1260 nm, extending to wavelengths above 2 m. The simulation also shows that the generated spectrum is highly coherent. We experimentally demonstrated the dispersion shift from anomalous to normal dispersion with the microstructure fiber fabricated in-house.

“…Chemical [15,16] and biological [17] suspended-core fiber absorption spectroscopy sensors, which exploit the absorbance characteristics of the light-matter overlap, provide opportunities for both environmental sensing and quantitative chemical analysis. Suspended-core fiber sensors using in-fiber excitation and recapturing [18] of fluorescent dyes [19] or quantum dots [20], as well as surface-enhanced Raman spectroscopy using nanoparticles [21], have also been shown to provide highly sensitive specificity of the analyte of interest.…”
