Successive Asymmetric Abrupt Tapers for Tunable Narrowband Fiber Comb Filters

Curvature investigation in tapered fibers and its application to sensing and mode conversion

“…Due to the different propagation velocities, an interference pattern is obtained at the output of the device. These are called non-adiabatic tapers and have been used not only in sensing applications [7][8][9] but also as filters [10][11][12] and dynamic pulse shapers [13].…”

Fabrication and Optical Characterization of Strain Variable PDMS Biconical Optical Fiber Taper

“…Tapers fabrication from optical fibers has led to formation of a large class of devices, such as optical fiber sensors [1], filters [2], modulators [3], couplers [4], etc. Most widely used materials for creating optical fiber tapers are various types of optical fiber glasses [5], [6], or polymers [7].…”
