WebWaveguide dispersion is important in waveguides with small effective mode areas . Examples are optical fibers, in particular certain photonic crystal fibers, but also other single-mode fibers as used in, e.g., optical fiber communications . Waveguide dispersion may be tailored via the fiber design to obtain the desired dispersion properties ... Web12 de abr. de 2024 · Two frequency-domain power monitors (M1 and M2) positioned above and below the GC are employed to measure the amount of optical power in upward and downward diffraction, and two additional power monitors (M3 and M4) positioned along the waveguide are used to assess the grating’s reflection and transmission.

The drive power and nonradiative decay are chosen such that ε B / γ 11 = 0.005 and γ nr / γ 11 = 0.01 , corresponding to a weak coherent drive tone in the strong-coupling limit. In an optical fiber, the normalized frequency, V (also called the V number), is given by where a is the core radius, λ is the wavelength in vacuum, n1 is the maximum refractive index of the core, n2 is the refractive index of the homogeneous cladding, and applying the usual definition of the numerical aperture NA.
