The Review of Laser Engineering, 2002 We describe the fundamentals of two new types of fiber, photonic crystal fiber (PCF) and photonic bandgap fiber (PBF). PCF is fabricated by forming small air holes in the cladding of the fiber rather than doping the fiber core with high-index materials.

Thin-film photonic crystal LEDs with enhanced directionality [PDF]
, 2009 The use of photonic crystals for light extraction from light-emitting diodes (LEDs) gives the possibility to shape the farfield emission pattern. This is of particular interest for étendue-limited LED applications that require a more directional ...

High-power supercontinuum generation with picosecond pulses [PDF]
, 2010 We investigate both theoretically and experimentally the properties of supercontinuum generation in the nearinfrared and visible regimes using high-power picosecond pulses propagating in a photonic crystal optical fiber. We discuss the effect of the pump

D-Shaped Photonic Crystal Fiber Toxic Metal Ions (Arsenic) Sensor Based on Surface Plasmon Resonance
Iraqi Journal of Physics, 2023 In this work, a Photonic Crystal Fiber (PCF) sensor based on the Surface Plasmon Resonance (SPR) technology was proposed. A thin layer of gold (Au) was deposited on a D-shaped Photonic Crystal Fiber (PCF), which was coated with plasmonic chemically ...

A new slant on photonic crystal fibers
Optics Express, 2004 We present the novel use of microstructured optical fibers not as 'light-pipes', but in a transverse geometry to manipulate the light propagating across the fiber. Fundamental and higher-order bandgaps were observed experimentally in this geometry using a number of techniques.
