A dense array of small coupled waveguides in fiber technology: trefoil channels of microstructured optical fibers (original) (raw)

Interest in the field of microstructured fibers was re-ignited in 1996 with the first demonstration of optical guidance within a complex 'holey' structure [2]. This new class of microstructured fiber, referred to as either Holey Fiber (HF), or Photonic Crystal Fiber (since the microstructure within the fiber is often highly periodic due to the fabrication processes used), provides a host of interesting and technologically enabling properties.
