Photonic crystal fiber coupler
Optics Letters, 2002Fiber couplers made with photonic crystal fibers (PCF) are reported. Two types of PCF were fabricated by means of stacking a group of silica tubes around a silica rod and drawing them. The fiber couplers were made by use of the fused biconical tapered method. With a fiber that had five hexagonally stacked layers of air holes, a 33/67 coupling ratio was

Highly Birefringent Photonic Crystal Fibers
Optics and Photonics News, 2000We report a strongly anisotropic photonic crystal fiber. Twofold rotational symmetry was introduced into a single-mode fiber structure by creation of a regular array of airholes of two sizes disposed about a pure-silica core. Based on spectral measurements of the polarization mode beating, we estimate that the fiber has a beat length of approximately 0.

Modeling of photonic crystal fibers
2007 19th International Conference on Applied Electromagnetics and Communications, 2007This paper presents an analysis and an overview of characteristics and possible applications of periodic and quasi-periodic photonic crystal fibers (PCF). The analysis is based on the decomposition of the transverse electric field into a series of orthogonal modes which are used to solve the vector wave equation for optical fibers.

AbstractReducing the complexity of opticalsystems emphasizes the need to increase the number of optical functions in as few modules as possible, making the system more compact and simple to operate. Optical functions such as light generation, frequency conversion, amplification, broadband transmission, wavelength filtering and interfacing to the ...

SPIE Proceedings, 2005
A brief review of three specially designed types of photonic crystal fiber (PCF) that we recently developed for high performance devices is presented. The first is absolutely single polarization PCF (ASPF), which guides only one polarization mode, the second is dispersion-flattened polarization maintaining PCF for Supercontinuum generation, and the ...

Elliptical-hole photonic crystal fibers
Optics Letters, 2001We study the dispersive properties of photonic crystal fibers (PCF's) with elliptical air holes. The unusual guidance of PCF leads to novel behavior of the birefringence, group-velocity walk-off, and dispersion parameters, including the possibility of zero walk-off with high birefringence in the single-mode regime. A number of these effects are closely

Optofluidic photonic liquid crystal fibers
2014 Proceedings of the 21st International Conference Mixed Design of Integrated Circuits and Systems (MIXDES), 2014Basic research directions in fiber-based optofluidics are discussed and in particular tunable optofluidic photonic liquid crystal fibers based on both silica-glass and polymer photonic crystal fibers are demonstrated. Experimental results on thermally-tunable light guiding mechanisms as well as selected optofluidic photonic liquid crystal fibers-based ...
