High index contrast
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. WebTo turn high contrast mode on or off from the sign-in screen, select the Ease of access button in the lower-right corner, then turn on the toggle under High Contrast. To turn high …
