| Abstract: | Photonic Crystal Fiber (PCF) is currently popular for their superiority of high power laser transmission, fiber amplifier, fiber laser and so on. Chalcogenide glass is a new kind of infrared (IR) glass fitting for IR fiber application, which possesses the good transparence in IR (1-20μm), high refractive index, high non-linearity, low phonon energy, adjustable components and good glass stability. Multi-pole method is first utilized to optimize the structure and properties of the PCF, then a combined fiber fabricating method is adopted based on extruding and stacking of the As2S3 chalcogenide glass. With this novel technique, a faviform PCF is obtained with three-layered circle-holes. The dispersion property and zero-dispersion spot are calculated and simulated on the basis of the multi-pole theory, and a near IR CCD is applied to observe the real type of the laser light transmission in the PCF with a wavelength of 1550nm. The size of the mode field and energy distribution in the fiber core are recorded and analyzed in a detail manner. The overall results may be of good help in validating the photon controlling theory and uncovering the truth of IR light transmitting effect in the IR PCF. |
