“…The full-vector finite difference method (FDM) [17,18] with anisotropic perfectly matched boundary layers (PMLs) is used to calculate the different properties of PCFs. Anisotropic PMLs absorbing boundary are positioned outside the outermost ring of air holes in order to reduce the simulation window and to evaluate the confinement loss of the proposed fiber with a finite number of air hole rings.…”

We propose broad supercontinuum spectrum generating highly nonlinear photonic crystal fiber (HN-PCF) which can be used in ultrahighresolution optical coherence tomography and optical transmission systems. Using full vector finite difference method, we investigated the different properties of HN-PCF. Broadband supercontinuum spectrum is numerically calculated by using nonlinear Schrödinger equation. Investigation showed that it is possible to obtain longitudinal resolution in a biological tissue of 1.3 μm, 1.2 μm and 1.1 μm by using picosecond continuum light at center wavelengths of 1.06 μm, 1.31 μm and 1.55 μm, respectively.

“…Holey fibers (HFs) [1] consisting of a central defect region surrounded by air holes running parallel to the fiber length have been one of the most interesting development in recent fiber optics [2]. HFs has emerging applications such as power delivery ultra-short pulse delivery, and pulse compression require refining and designing other characteristics, most notably increased bandwidth, near-zero flat chromatic dispersion, and control of the nonlinear responses [3].…”

We propose a four-ring hexagonal holey fiber (HF) which exhibits near zero ultra-flattened chromatic dispersion and nonlinear property simultaneously in a modest number of rings. The finite element method with perfectly matched layers boundary condition is used to investigate the guiding properties. A four ring HF with flattened dispersion of 0.85ps/nm/km from 1.14 to 1.60 µm wavelength range, 21.34W-1km-1 nonlinear coefficient and splice loss 3.82 dB at 1.55µm is numerically demonstrated.

“…Like different structural shape, geometrical parameters of fiber are also responsible to vary guiding properties [13]. Some different lattice structures like octagonal [14], hexagonal [15], decagonal [16], circular honey comb cladding [17], elliptical [18] were proposed to achieve the better guiding properties of photonic crystal fiber (PCF).…”

Abstract.A hybrid structure photonic crystal fiber gas sensor is presented in this paper to detect toxic and colorless gases. The guiding properties of proposed structure have been numerically investigated using finite element method (FEM). From the numerical results sensitivity of the proposed structure is enhanced to 15.67%. The Confinement loss or Leakage loss decreased to 1.12×10-7 by acquainting an octagonal ring of air holes in the outer cladding. The proposed H-PCF can be used in a wider range of wavelength from 0.8µm to 2 µm. The proposed structure has significantly lower confinement losses, higher sensitivity and is more flexible for its simplicity compared with early proposed PCFs.Keywords: Hybrid Photonic Crystal Fiber (H-PCF), Evanescent Field, Gas Sensor, Sensitivity, Finite Element Method and Confinement Loss. Hibrit Kaplamaları Photonıc Kristal Fibere Dayalı Basit Yapılı Gaz Sensörü TasarımıÖzet. Bir melez yapılı fotonik kristal fiber gaz sensörü, toksik ve renksiz gazları algılamak için, bu çalışmada sunulmuştur. Önerilen yapının yol gösterici özellikleri sayısal sonlu elemanlar metodu (FEM) kullanılarak incelenmiştir. Sayısal sonuçlardan önerilen yapı duyarlılığı %15.67'e yükseltilmiştir. Hapsetme kaybı ya da kaçak kaybı, dış cephe hava deliklerinin sekizgen halka yapısı ile 1.12 × 10 -7 değerine düşmüştür. Önerilen H-PCF, 0.8μm ile 2 um dalga boyu aralığında kullanılabilir. Önerilen yapı, daha düşük hapsi kayıpları, yüksek duyarlılık sahibidir ve önceden önerilen PCFs ile karşılaştırıldığında sadeliği için daha esnektir.
