Tellurite photonic crystal fiber
Optics Express, 2003 We report the fabrication of a Tellurite photonic crystal fiber, and demonstrate its waveguiding properties. The measured minimum loss is 2.3 dB/m at a wavelength of 1055 nm. The fiber supports several modes, but in practice just the fundamental mode can be used. We have observed strong stimulated Raman scattering in a fiber with an effective area Aeff=

Design of a highly-birefringent microstructured photonic crystal fiber for pressure monitoring [PDF]
, 2010 We present the design of an air hole microstructured photonic crystal fiber for pressure sensing applications. The air-hole photonic crystal lattices were designed to produce a large intrinsic birefringence of 1.16x10-3. The impact of the surrounding air

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
