In addition, the disturbance (4) introduced into the core to control the total dispersion. 使波导预选段(6,8)的总色散改变符号,这样,总色散与长度(13,15)乘积之和在代数上加到一个预选值. Preselected segment of the waveguide (6,8) of the total dispersion changes sign, so that the total ...
In the context of waveguide theory, dispersion is defined as the change in the specific group delay of the signal with wavelength. It is related to the propagation constant by: (11.5)D=ddλ(1cdβdk), which can be directly calculated from the solution of the scalar wave equation (Eq. ...

This results in a waveguide contribution that must be added to the material contribution to obtain the total fiber dispersion. Laser pulses have a spectral broadening Δω, normally much smaller than the central frequency ω0. This allows one to treat the wave propagation in a dispersive medium ...
dispersion is caused; the final waveguide dispersion, mainly in the single-mode optical transmission, the width and frequency band remain unchanged, and the tangent component is different, and finally caused The dispersion. Waveguide dispersion and material dispersion are also collectively referred to ...
The rectangle waveguide is with the width of w and interior dielectric with permittivity of ε r , as illustrated in Figure 1. Due to the transverse resonance, it is known that the TE10 mode propagating in the rectangle waveguide has a propagating constant β = k 0 (ε r − (λ/2w)...

It is composed or two factors: material dispersion, a measure of the change in refractive index of the glass with wavelength, and waveguide dispersion. The latter dispersion component is due to the fact that the light travels partially in the core and partially in the cladding, and the ...
