Webhigh-index-contrast boundaries. For high-index-contrast waveguides, however, the linear relationships between the electric and magnetic fields (Eqs. (1) and (2)) do not hold since they must satisfy different boundary conditions. This is shown in Fig. 1. For low-index-contrast waveguides, Eqs. (1) and (2) are close approximations. Web1 de jan. de 2024 · As a consequence, the light confinement from the low-index-contrast periodic cladding is weak and thereby the leaky loss is very high. In contrast, the SCBFs with high-index-contrast claddings are capable of much stronger light confinement in the core by using the photonic bandgap (PBG) effect.
