Microstructured and Photonic Bandgap Fibers for Applications in the Resonant Bio- and Chemical Sensors
Figure 2
Various types of hollow core photonic bandgap fibers. (a) Bragg fiber featuring large hollow core surrounded by a periodic sequence of high and low refractive index layers. (b) Photonic crystal fiber featuring small hollow core surrounded by a periodic array of large air holes. (c) Microstructured fiber featuring medium size hollow core surrounded by several rings of small air holes separated by nano-size bridges.
