Tidskriftsartikel (refereegranskat)abstract
- We demonstrate a highly tunable photonic bandgap fiber, which has a large-core diameter of 25 μm and an effective mode area of 440 μm 2. The tunability is achieved by infiltrating the air holes of a photonic crystal fiber with an optimized liquid-crystal mixture having a large temperature gradient of the refractive indices at room temperature. A bandgap tuning sensitivity of 27 nm/°C is achieved at room temperature. The insertion loss is estimated to be less than 0.5 dB and caused mainly by coupling loss between the index-guided mode and the bandgap-guided mode.

Konferensbidrag (refereegranskat)abstract
- A new class of hybrid photonic crystal fibers infiltrated with liquid crystals offers novel functionalities and ultimately takes full advantage of the different waveguiding effects demonstrated today. Among the most interesting possibilities, we demonstrate 'distributed' tunable filter and switching functionalities operating by the photonic bandgap effect.
