Fabrication of Photonic Crystal Fiber Gratings
This article will review our research work on fabrication of those gratings in PCFs by use of focused beam from a CO 2 laser and point-by-point writing fashion. Either the mechanical stress relaxation technique or surface deformation method is employed in the design and fabrication of. The photonic crystal fiber (PCF) is a special class of components incorporating photonic crystals with a two-dimensional (2D) periodic variation in the plane perpendicular to the fiber axis and an invariant structure along it [1-3]. Post processing of PCFs with a CO 2 laser is very powerful and. with ethanol) into the hollow core photonic crystal fiber (HC19-1550 (Thorlab company)). This stage is capable of moving the fibers in micrometer.
