Transmittance of tapered photonic crystal fibers with absorbing coatings [PDF]
EPJ Web of Conferences, 2020 The interaction of the adiabatically tapered photonic crystal fiber fundamental mode with a thin-film absorbing coating, deposited on a surface of a taper waist, on transmission of a tapered fiber is studied.

Multimaterial photonic crystal fibers [PDF]
Optical Components and Materials XV, 2018 One of the main advantages of photonic crystal fibers (PCFs) is their ability to host novel functional materials in the airholes of the cladding. Here, we demonstrate a unique post-processing method which allows the integration of materials with significantly different thermo-mechanical properties inside the voids of silica PCF.

Fiber fuse in chalcogenide photonic crystal fibers [PDF]
Optics Letters, 2018 We observe fiber fuse in tapered GeAsSe photonic crystal fibers (PCF) at around 7 MW/cm2 of intra-core intensity. Vertically cleaved facets from the un-tapered regions and the tapered regions were imaged. The images show shallow voids of different shapes confined to the fiber core. After longitudinally polishing a segment of the PCF, we imaged the PCF

Design of temperature sensor using twisted photonic crystal fiber
Results in Physics, 2018 We proposed a novel temperature sensor based on dual core photonic crystal fiber (DCPCF) and applying different twisting on its cladding surface. The temperature dependent chloroform is applied as analyte.

Fiber transport of spatially entangled photons [PDF]
, 2011 Entanglement in the spatial degrees of freedom of photons is an interesting resource for quantum information. For practical distribution of such entangled photons it is desireable to use an optical fiber, which in this case has to support multiple ...

Depolarized guided acoustic wave Brillouin scattering in hollow-core photonic crystal fibers
, 2015 By performing quantum-noise-limited optical heterodyne detection, we observe polarization noise in light after propagation through a hollow-core photonic crystal fiber (PCF).

Optics Express, 2006 We present a hybrid photonic crystal fiber in which a guided mode is confined simultaneously by modified total internal reflection from an array of air holes and antiresonant reflection from a line of high-index inclusions. Experimental results demonstrate that this fiber shares properties of both index-guided and photonic bandgap structures.
