THEORY OF QUASI LP-MODES IN ANISOTROPIC OPTICAL PIBRES

摘要

INTRODUCTIONIt is known[1-4], that LP-modes exist in isotropic fibres, if △ε=εco-εce→O,Ka→∞,o＜V＜∞,where ∨=Ka(εco-εce)1/2,k=aπ/λ,a is the core radius, εco and εce are core and cladding permittivity. In anisotropic fibres with tensors permittivity.
