“…Moreover, this design scheme essentially focuses on the light transmission through core modes only, unlike the quasi-periodic fiber geometry presented in (Hu et al, 2012) to capture light through cladding modes. In this context, a similar concept of concentric multiple cores in a conventional index-guided fiber has been reported recently for optical communication to address the issue of capacity crunch (Nadeem and Choi, 2016;Bairagi et al, 2019).…”

Photonic bandgap (PBG) fibers provide a versatile platform for ultra-short pulse delivery with low-loss, and low dispersion. Precisely, Braggkind of 1D PBG fibers with periodic cladding bilayers offer ample degrees of freedom to tailor fiber bandwidth along with loss, and dispersion. In this paper, we propose a next-level specialty bandgap fiber with multiple concentric cores based on the 1D PBG geometry in an all-solid form. It has three sets of tailored bilayer thickness in which each set of bilayer forms an effective core region that allows confinement of specific range of wavelengths. Thus, the successive overlap of the wavelength ranges supported by each of these concentric cores effectively enhances the overall transmission bandwidth of the fiber. Moreover, the concept can be extended to form a large number of concentric cores that allows further enhancement of the fiber bandwidth. As a proof-of-concept, an ultra-wide low-loss bandwidth covering a wavelength range of ~ 1600 nm for the fundamental mode has been achieved. Going beyond, an advanced level customization of the proposed fiber geometry has enabled further minimization of loss and enhancement in structural robustness. The propagation dynamics of an ultrashort pulse ~ 300 fs have been investigated numerically in both the normal and the anomalous dispersion regime of the proposed specialty fiber in the presence of nonlinearity and loss. Eventually, such all-solid multicore large-bandwidth fiber is proposed as a promising candidate for the delivery of ultrashort optical pulses over long distance with minimum amount of distortion and wave-breaking possible.

“…A large transmission rate has been attracting increasing interest because of the rapid spread of Web organizations [1]. According to this trend, in current fiber-optic systems, the transmission distance and channel capacity continued significantly to increase by using optical amplification and wavelength-division multiplexing (WDM).…”

Dispersion-managed optical link with optical phase conjugator (OPC) at the midway is well known for the compensation technique of optical signal distortion due to group velocity dispersion and fiber nonlinearities. However, in this link, the midway position of OPC restricts the flexible optical link configuration. That is, the OPC position has to get out of the midway for implementation of the flexible link configuration. Therefore, the proponents of this study demonstrated the compensation effect of the non-midway OPC in dispersion-managed optical link on the distorted wavelength division multiplexed (WDM) channels. It is confirmed in this study that the non-midway OPC is somewhat effective in the compensation depending on the detailed link parameters. It is also confirmed that when the OPC was moved to transmitter or receiver of WDM system from the midway, it becomes desirable to control the net residual dispersion (NRD) in one transmission section having the lower fiber span number, and simultaneously select the start fiber span of that transmission section as the position of NRD control.
