| Abstract(in English) | SOI (silicon-on-insulator) wafers became popular platforms for photonic integration. Rib waveguides on the SOI wafers have been attracted more attentions due to the advantages, such as low loss, low polarization-dependence and easy fabrication. However, the conventional SOI rib waveguides with a large mode size suffer from bending loss, and the silicon-wire waveguide with a small mode size from a large transmission loss. Here we give a new design of a SOI rib waveguide with a medium mode size. For single-mode waveguides, the bending radius of the new SOI rib waveguide is 1/10 of that of a conventional SOI rib waveguide with a large mode size. In the case of the same surface roughness, the new SOI rib waveguide has a less transmission loss than the silicon-wire waveguide. We fabricated and evaluated the new SOI rib waveguides. The transmission loss and bending radius of the single-mode waveguide are 2dB/cm and 1mm, respectively. These results show that the SOI waveguides with a medium mode size are feasible ones for photonic integrated circuits. |
