Title:
HYBRID PHOTONIC CRYSTAL FIBER, AND METHOD FOR MANUFACTURING SAME
Document Type and Number:
WIPO Patent Application WO/2012/096515
Kind Code:
A2
Abstract:
The present invention relates to a hybrid photonic crystal fiber, into the core of which a functional material is injected. The hybrid photonic crystal fiber of the present invention comprises: a cavity extending in a lengthwise direction through the center of the photonic crystal fiber and having a diameter of 4 to 15 µm; an inner clad which is formed along an outer surface of the cavity and which extends in the lengthwise direction of the photonic crystal fiber such that a plurality of air holes, each having a diameter of 2 to 5 µm, are formed into a hexagonal shape around the cavity, wherein the spacing between the air holes is 4.5 to 7 µm; a ring-shaped outer clad which covers an outer periphery of the inner clad; and a core formed by injecting a functional material into the cavity and air holes. According to the present invention, changes in the state, i.e. the liquid, liquid-crystal, or biofluid states, of the functional material that fills the core that has a variety of shapes may enable the modulation of light intensity, wavelength, phase, and polarization, and thus enable various photonic networks to be produced. The hybrid photonic crystal fiber of the present invention may serve as various optical sensors capable of sensing changes in refractive index caused by external stresses such as temperature and pressure. The hybrid photonic crystal fiber of the present invention may be used as a light source for a fluorescent dye laser for a visible ray zone using fluorescent dye, or for an ultra-wideband laser of 700 nm or higher using high nonlinear liquid.
