“…The negative dispersion of PCF can be used for dispersion compensation. Due to large value of negative dispersion as compared to conventional fiber, short length of PCF can be used for dispersion compensation, thus reducing the loss [27]. For ellipticity ratio of 1.5 the value of dispersion is −338 ps/nm-km for PCF.…”

“…where is the Sellmeier coefficient. Chromatic dispersion in PCF can be adjusted by various methods [18], either by changing the arrangement of air holes or with the number of air holes, and also with the shape of the air holes in the cladding region. Properly designed PCFs with large negative dispersion coefficient value can be used for dispersion compensation [19,20].…”

We propose and design a spiral photonic crystal fiber with elliptical air holes for achieving high birefringence, large nonlinearity, and negative dispersion. The structure is designed using chalcogenide glass (As2S3) for different ellipticity ratios of air holes in the cladding and the effect on various properties is observed. The proposed structure has birefringence of the order 10−2, nonlinearity of 26739.42 W−1 m−1, and dispersion of −1136.69 at 0.85 μm. An accurate numerical approach based on finite element method is used for the design and simulation of the structure. Due to high birefringence and negative dispersion, the proposed structure can be used for polarization control and dispersion compensation, respectively.

“…In this regard, photonic crystal fibers (PCFs) are one of the most efficient media where the endless single-mode propagation can be achieved by the special geometry arrangement of cladding and core. In this work, instead of the conventional air-hole PCF structure in which precisely controlling the dimension of air holes in fiber fabrication is quite demanding and labor-intensive, the all-glass PCF structure is proposed where the air holes are replaced by the commercially available fluorine-doped silica rods, similar to the ones reported in [ 26 , 27 ]. The core and cladding have an extremely low refractive index difference of Δ n ~1.2 × 10 −3 .…”

The advent of the ‘lab-on-fiber’ concept has boosted the prosperity of optical fiber-based platforms integrated with nanostructured metasurface technology which are capable of controlling the light at the nanoscale for multifunctional applications. Here, we propose an endless single-mode large-mode-area photonic crystal fiber (LMA-PCF) integrated metalens for broadband and efficient focusing from 800 to 1550 nm. In the present work, the optical properties of the substrate LMA-PCF were investigated, and the metalens, consisting of dielectric TiO2 nanorods with varying radii, was elaborately designed in the fiber core region with a diameter of 48 μm to cover the required phase profile for efficient focusing with a high transmission. The focusing characteristics of the designed metalens were also investigated in detail over a wide wavelength range. It is shown that the in-fiber metalens is capable of converging the incident beams into the bright, symmetric, and legible focal spots with a large focal length of 315–380 μm depending on the operating wavelength. A high and average focusing efficiency of 70% was also obtained with varying wavelengths. It is believed the proposed fiber metalens may show great potential in applications including fiber laser configuration, machining, and fiber communication.

“…The recent years has gained attention for device design in optical domain for all optical processing. The conversion of electrical to optical and vice versa requires switches for the end processing of device design so it is very essential to develop all optical devices [1]. The encoder is a combinational circuit for data encryption in the digital design.…”

The proposed encoder in two dimensional photonic crystals is analyzed interms of ow of light inside waveguides.Waveguides have been created by removing silicon rods in the structure and defects with smaller radii have been created to achieve the proper couplers operations. The photonic band gap of the proposed encoder is determined and their performance is evaluated using nite difference time domain method. The proposed design has an optical output power threshold range between 76-94% for ON state and threshold level of OFF state is below 20%. The proposed encoder is operated in the wavelength of 1550 nm. Hence, it is applicable for high speed optical integrated circuit. The response time and contrast ratio calculated from the proposed encoder are 0.24 ps and 8.59 dB which are comparatively better than the literature reported with compare to footprint area of the proposed encoder.
