Scope of this special issue

Periodic optical nanostructure affecting the characteristics of photons leads to a photonic crystal. An optical fiber with the property of photonic crystal is known as photonic crystal fiber (PCF). For the first time, it was explored in 1996. It plays a vital role as the main pillar of modern telecommunication. In PCFs a high refractive index material, e.g., silica, is used as background material which is doped in a periodic manner with the low refractive index material, e.g., air holes. The optical characteristics of PCF can be changed by altering its geometry like shape, size, filling material, and pitch of holes. In contrast to conventional fiber, PCF has many advantages e.g., high nonlinearity and highly negative dispersion with very low confinement loss, tunable and high birefringence, high effective area, polarization-maintaining capability.

    The high-speed internet is becoming the essential need of the current generation of mobile communication, i.e., 5G or higher technology. Therefore, wavelength division multiplexing (WDM) and further DWDM techniques are being used to enhance the data rate. But the data rate is limited by the chromatic dispersion because it broadens the data pulses in the long-haul transmission. Further, the data rate can be increased by adding another degree of freedom by including the polarization. Highly negative dispersion of PCF can be used to compensate the dispersion during high data rate. There is a need for physically reliable and cost effective PCF having highly negative dispersion coefficient along with low-nonlinearity, low birefringence, low confinement loss and material loss.

    The conventional fibers are limited for applications in versatile fields such as: high power physics, nonlinear fiber optics, metrology, sensing applications, optical coherence tomography, and quantum dots. In light of the above issues of the conventional fibers, this research topic draws the attention of the researchers towards the following scope of research under PCF for communication:

1. Highly negative dispersion coefficient along with other improved performance parameters such as: low-nonlinearity, low birefringence, low confinement loss, and low material loss.

2. High power handling capacity

3. Simpler design of the needed PCF which can be fabricated physically.

4. The uniformity of the design parameters throughout the length of the PCF.

Authors may submit both original research and review articles in regard of the above research scope.
