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. 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. rocky mount nc social services https://americanffc.org
