Novel Square Photonic Crystal Fibers with Ultra-Flattened Chromatic Dispersion and Low Confinement Losses

Supercontinuum generation in square photonic crystal fiber with nearly zero ultra-flattened chromatic dispersion and fabrication tolerance analysis

“…[19] inserted an extra air hole between two consecutive air holes which imposes fabrication challenges. In our other previous work [20], the proposed SPCF demonstrated flattened [13] and theoretically [22] that small parameter deviations from the target design, due to fabrication inaccuracies can lead to a significant deviation from the anticipated dispersion properties. Understanding the sensitivity of the dispersion properties to fabrication errors for different structural designs is thus an important issue.…”

“…Conventional PCF designs are those that have air holes with the same diameter [11][12][13][14], others include structures with two-defective air hole rings [15], nonlinear PCFs with several kinds of air hole diameters [16][17][18], modified hexagonal PCFs [19], square PCFs [20] and polarization maintaining highly nonlinear PCF [21]. The PCFs' structure in ref.…”

Simulation analysis of a temperature sensor based on photonic crystal fiber filled with different shapes of nanowires

“…Many studies attempted to confine the plasmonic modes within the PCF through incorporating metallic layers or metallic nano-materials into it [13][14][15]. And various PCF designs have been proposed to control different transmission properties, such as hexagonal PCFs, square PCFs and octagonal PCFs [16][17][18]. Additionally, the polarization properties of various PCFs can be manipulated by filling the air holes with polymer [19], oil [20], gas [21], liquid [22], or liquid crystal [23].…”

Photonic Crystal Fiber for Medical Applications

“…Currently, it is reported that the OCT imaging at 1.5 ~ 1.6 m broadband light source can be readily applied to take images of human tooth samples [Lee et al, 2009]. On the other hand, telecommunication window (around 1.55 m) is the most attractive window in optical communication systems, dispersion compensation and nonlinear optics because of the minimum transmission loss of the fiber [Begum et al, 2007a[Begum et al, , 2007b[Begum et al, , 2009a. Photonic crystal fibers (PCFs) [Russel, 2003], a pure silica core optical fibers with tiny air holes embedded in the host silica matrix running along the propagation axis, have boosted the fiber optic research due to their remarkable modal properties such as provide singlemode operation for very short operating wavelengths [Knight et al, 1996], remain singlemode for large scale fibers [Knight et al, 1998], achieve high birefringence [Kaijage et al, 2000], and controllable dispersion characteristics [Begum et al, 2009b] which cannot be achieved with conventional optical fibers.…”
