Broadband Silicon Nitride Power Splitter Based on Bent Directional Couplers with Low Thermal Sensitivity

Directional couplers, as power splitters, have provided a significant contribution for light splitting and combining in silicon photonics. However, the splitting ratio of conventional directional couplers is very sensitive to wavelength, which limits the bandwidth and the transmission performance of...
