Various embodiments may provide an optical fiber for sensing an analyte. The optical fiber may include a dielectric core wall defining a hollow space. The optical fiber may also include a cladding layer surrounding the dielectric core wall and spaced apart from the dielectric core wall. The optical fiber may further include a plurality of supports extending from the cladding layer to the dielectric core wall. A thickness of the dielectric core wall may be greater than a thickness of each of the plurality of supports. The dielectric core wall may be configured to carry an optical light for sensing the analyte.

An optical element is provided. The optical element may comprise a material, the material being a matrix and a set of particles included in the matrix, the material having a molar fraction of SiOhigher than or equal to 65 percent, each particle having a dimension smaller than or equal to 80 nanometers.

Optical element and associated manufacturing method

The present application discloses a surface-enhanced Raman scattering (SERS)-active photonic crystal fiber (PCF) probe including a biopsy needle in the PCF probe for integrated sample collection and SERS sensing of one or more analytes comprised in the sample. The PCF comprises solid core and a cladding region surrounding the solid core, wherein the cladding region comprises air holes functionalised by metallic nanoparticles. The application also provides a method for detecting one or more analytes using the PCF probe as well as the use of the PCF probe for the detection of one or more analytes.
