چکیده
Both nonlinear effects and dispersion are important factors that affect the transmission of optical pulses in fibres. In anomalous region, mutual balance can achieve soliton transmission. Starting from Schrodinger equation pulse, under condition ignoring dispersion, phase shift frequency chirp Gaussian pulse effect self-phase modulation (SPM) derived simulated; numerical simulation SPM spectrum with different maximum shifts without positive chirp. The study found fusion loss fibre obtained by this algorithm is less than 0.11dB traditional single-mode fibre, additional bending caused wavelength range 1460nm to 1625nm after winding 100 times on a 60mm cylinder 0.02dB/km.

متن کاملNonlinear limits to the information capacity of optical fiber communications
The exponential growth in the rate at which information can be communicated through an optical fiber is a key element in the so called information revolution. However, like all exponential growth laws, there are physical limits to be considered. The nonlinear nature of the propagation of light in optical fiber has made these limits difficult to elucidate. Here we obtain basic insights into the ...
متن کاملHighly Nonlinear Dual Core Photonic Crystal Fiber with Low Confinement Loss at 1.55μm Wavelength
A novel design of Dual-Core Photonic Crystal Fiber (DC-PCF) with silica-air microstructures is proposed in this paper. Nonlinearity and confinement loss of DC-PCF are evaluated by using a Full-Vectorial Finite Element Method (FV-FEM) successfully. By optimizing the geometry of three ring DC-PCFs, a high nonlinearity (52w-1km-1) and low confinement loss (0.001dB/km) can be achieved at 1.55μm wav...
