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.

WebHigh-index contrast dielectric waveguides exhibit strong confinement, making the TE and TM modes very different. As a result, device characteristics, such as propagation constant and coupling strength become strongly polarization dependent. Webhigh coupling efficiency of ~1.3 dB [21] has been recently demonstrated between a tapered fiber and the moderate-index-contrast LN waveguide with the Ta2O5 cladding, the same technique cannot be directly implemented on the high-index-contrast waveguides because of the much smaller mode diameters.
