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

Optical fiber-based measurement of ultra-small mode volume and a high quality factor in a photonic crystal microcavity [PDF]
, 2004 Using an optical fiber taper that simultaneously probes the spectral and spatial properties of resonant cavity modes, two-dimensional Si photonic crystal microcavities with a quality factor Q~40,000 and modal volume V_eff ~0.9(λ/n)^3 are experimentally ...

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
