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.

Tapered photonic crystal fibers
Optics Express, 2004 We demonstrate the tapering of a photonic crystal fiber to achieve a microstructure pitch of less than 300 nm. We probe the tapered fiber in the transverse geometry to demonstrate the scaling of the photonic bandgaps associated with the microstructure.

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=

The radiated fields of the fundamental mode of photonic crystal fibers [PDF]
, 2005 The six-fold rotational symmetry of photonic crystal fibers has important manifestations in the radiated fields in terms of i) a focusing phenomena at a finite distance from the end-facet and ii) the formation of low-intensity satellite peaks in the ...

Mode degeneration in bent photonic crystal fiber study by using the finite element method [PDF]
, 2009 The development of highly dispersive lower and higher order cladding modes and their degeneration with respect to the fundamental core mode in a bent photonic crystal fiber is rigorously studied by use of the full-vectorial finite element method.
