Fig. 6From: Tapered photonic crystal fibers coated with ultra-thin films for highly sensitive bio-chemical sensingCalculated integral transmittance of the investigated hydrogen sensor versus a hydrogen concentration (left) and a sensor sensitivity for different waist lengths L0 (right). Curves 1 and 2 are calculation results for lengths L0 = 10.00 mm and 6.374 mm, respectively. Circles are experimental resultsBack to article page
