The group delay and group velocity dispersion (GVD) of the fundamental mode was proposed by derivative action on the characteristic equation directly and the influence of different index contribution of doubly clad single-mode fibers on propagation constant, group delay, group velocity dispersion and the zero dispersion wavelength were studied.
The research results indicate that the optical parameters, i.e., relative index of inner clad and outer clad (R) and relative index of the core and outer clad (P), have distinct impact on propagation constant, group delay, group velocity dispersion and zero dispersion wavelength and the rules of impact vary with the parameters.
The amplitudes of four wave mixing in different optical fiber chains are compared. In order to decrease the four wave mixing effect, the fiber with zero dispersion wave close to the signal optical pulse should be put far away Er doped fiber amplifier in each amplifier spacing.
By tuning the fs-pulsed Ti:Sapphire laser to the zero dispersion wavelength of the PCF, the spectral and temporal properties of the source are largely unaffected and hence this source can easily be used for MPLSM.
Compression of sub-nanojoule laser pulses using a commercially available photonic crystal fiber (PCF) with zero dispersion wavelength of 860?nm is discussed.
When β3 is negative and the zero dispersion wavelength is set at the longer wavelength side than the pump wavelength, such as around 2 μm, it is possible to convert the generated soliton into new components at the longer wavelength side over 2 μm.
To minimize the walk-off between two wavelengths, we chose the input signal and the desired output signal wavelengths, equally spaced on opposite sides of the zero dispersion wavelength of the fiber.
To minimize the walk-off problem between two wavelengths, we chose pump signal and control signal to be equally spaced on opposite sides of the zero dispersion wavelength of the fiber.
Employing optical sources with different wavelength as the input optical signals of WDM system, the phenomenon of four wave mixing in the experiment is analyzed. The amplitudes of four wave mixing in different optical fiber chains are compared. In order to decrease the four wave mixing effect, the fiber with zero dispersion wave close to the signal optical pulse should be put far away Er doped fiber amplifier in each amplifier spacing. The experimental phenomena are theoretically analyzed.
