摘要
Numerical simulations are used to investigate the guiding properties of large mode area silicon microstructured fibers. Modal analysis of the isolated high refractive index core and cladding rod inclusions will be applied to show that the guidance mechanism of the composite fiber can be well described via a hybrid of the total internal reflection and antiresonant reflecting optical waveguide models. It will be shown that by selectively filling the cladding holes with silicon, which has been modified to have a slightly raised index, the fiber can be designed to operate in an effectively single-mode regime over an extended wavelength range.
