Paper Abstract
Optical beam splitters form a fundamental component in integrated optical systems, performing as modulators,
interferometers and (de)multiplexers. While silica is a desirable material, because of its low non-linear susceptibility, it is
extremely challenging to achieve the requisite core-clad refractive index contrast. In this work, silica splitters with an
effective refractive index difference of 25% between the core and clad is demonstrated. The splitter can divide power
evenly with low crosstalk from 1520 to 1630nm. In addition, the splitting ratio doesn't change and the output power
increases linearly with the input power, which indicates a low susceptibility to thermal effects. The splitter's polarization
independent behavior is also verified.
