Comparison between Different Structures of Suspended-Core Microstructured Optical Fibers for Volatiles Sensing.

In this paper, different core structures of microstructured optical fibers (MOFs) for low-finesse Fabry⁻Pérot (FP) sensors are experimentally compared to get the highest sensitivity. These devices are designed for volatile organic compounds (VOCs) measurements. Indium tin oxide (ITO) thin films were deposited by sputtering on the MOFs and different optical fast Fourier transform (FFT) phase responses from the FP were measured for saturated atmospheres of ethanol.
