Hexagonal Photonic Crystal Fiber Behaviour as a Chromatic Dispersion Compensator of a 40 Gbps Link

Abstract

In this paper, the capabilities of chromatic dispersion compensation of a photonic crystal fiber with a hexagonal distribution of circular air holes was investigated. The vector finite element method with scattering boundary condition was used to analyze a set of configurations of the fiber in which the distance between air holes’ centers was modified. With this method it was possible to obtain the values of chromatic dispersion and confinement factor in the C fiber band. The best suited configurations were tested in a 160 km optical link with a bit rate of 40 Gbps. The performance was evaluated by measuring the bit error rate for a set of 20 channels with channel spacing of 100 GHz. The simulation results showed that is possible to reach values of chromatic dispersion as low as $- 850{{{\rm{ps}}} \over {{\rm{nm}} \middot {\rm{km}}}}$ , confinement losses close to 10−3 dB/km and good BER results in the order of 10−17 for a wavelength of 1550 nm.

Optimization and Performance Analysis of Dispersion Compensation in RZ and NRZ Systems with Transmission Rates of 10 Gbps and 40 Gbps / Otimização e Análise da Compensação de Dispersão em Sistemas de RZ e NRZ com Taxas de Transmissão de 10 Gbps e 40 Gbps

“…Special fibers are called optical dispersion compensators (ODCs), which are based on linear and nonlinear phenomena. In ODCs, dispersion occurs in the optical domain, so there is no additional latency in the network, unlike electronic dispersion compensators (EDCs), in which delays occur in the electronic approach (BETANCUR-PÉREZ et al, 2017).…”

Design of Low-loss and Highly Birefringent Porous-Core Photonic Crystal Fiber and Its Application to Terahertz Polarization Beam Splitter

“…Another important parameter in THz-PCFs is the dispersion, because it limits the quality of the signal transmission on optical links. The dispersion effect can induce a pulse broadening, which causes inter-symbol interference among the different signals that travel simultaneously on the fiber [26], [41], [44].In addition, low dispersion and dispersion-flattened profile are particularly suitable for broadband signal transmission. The background material and the structural geometry might cause dispersion.…”

Dual-Core Transversally Chirped Microstructured Optical Fiber for Mode-Converter Device and Sensing Application

“…Another interesting alternative is to use microstructured optical fibers (MOFs), also called photonic crystal fibers (PCFs), which offer flexibility in its design and the possibility of manipulating the optical properties of the device because its characteristics-dispersion, effective area, birefringence and nonlinearity, among othersdepends on the diameter of holes, the separation between them and the shape of the microstructure [11][12][13][14][15][16][17]. Owing these characteristics, these type of optical fibers have been employed for the development of different devices such as polarization beam splitters [18], dispersion compensators [19,20] and mode converters [5] to name a few.…”
