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

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 ...

Characterization of 1D photonic crystal nanobeam cavities using curved microfiber [PDF]

, 2010
We investigate high-Q, small mode volume photonic crystal nanobeam cavities using a curved, tapered optical microfiber loop. The strength of the coupling between the cavity and the microfiber loop is shown to depend on the contact position on the ...
