A quasidistributed fiber sensor for solute concentration measurement based on Fresnel reflection from fiber tips and the interrogation of an arrayed waveguide grating is presented. Thin-film filters are utilized to achieve the possibility of wavelength-division-multiplexing distributed sensing. The experimental results can be fitted to a linear equation very well, with a value of R2 larger than 0.993. The quasidistributed sensor exhibits a capability for real-time, remote measurement of concentrations with high precision, and offers a solid structure, low cost, and easy implementation.
