| Popis: | We report compact and low loss silicon nanophotonic waveguide transitions, to connect different cross-sections of routing waveguide in large photonic integrated circuits. 25- $\mu \text{m}$ -long tapers shaped as a stretched sinusoid had 0.029 ± 0.002 dB absolute loss between single-mode strip and multi-mode rib waveguides. 10- $\mu \text{m}$ -long adapters of concave elliptic shape had 0.002 ± 0.001 dB absolute loss between single-mode strip and rib waveguides, the lowest reported loss for such adapters. |
