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 central hole having a diameter of 4 to 15 μm extending in the longitudinal direction; an inner cladding also formed in the longitudinal direction outside the central hole, having a hexagonal arrangement of air holes, each of which has a diameter of 2 to 5 μm and a lattice constant of 4.5 to 7 μm; an annular outer cladding surrounding the outer surface of the inner cladding; and a core formed by filling a functional material in some of the air holes including the central hole. 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.
