@article{Ma_Bock_2013, title={Evanescent-wave Sensing with Multiple Sampling Channels along a Single Optical Fiber}, volume={5}, url={https://www.photonics.pl/PLP/index.php/letters/article/view/5-58}, DOI={10.4302/photon. lett. pl.v5i4.452}, abstractNote={We demonstrate that the evanescent-wave sensing platform with one sampling channel may be expanded to at least a 12-channel system. These channels are implemented as a series of 2-mm long exposed segments of the fiber core sidewall along a single optical fiber. Using the cladded fiber segments as channel separations, we achieve a condition of zero inter-channel crosstalk, which is fundamental to the system operation, for both 4- and 12-channel systems. Theoretical interpretation of the mechanism of zero inter-channel crosstalk is examined in detail. <br /> <br /> Full Text: <a class="file" href="/PLP/index.php/letters/article/view/5-58/318" target="_parent">PDF</a> <br /> <br /> <strong>References</strong> <ol> <li>C.
