Ultralow-loss compact silicon photonic waveguide spirals and delay lines
文献摘要：
Low-loss and compact optical waveguides are key for realizing various photonic integrated circuits with long on-chip delay lines,such as tunable optical delay lines,optical coherence tomography,and optical gyroscopes.In this paper,a low-loss and compact silicon photonic waveguide spiral is proposed by introducing broadened Archimedean spiral waveguides with a tapered Euler S-bend.A 100-cm-long waveguide spiral is realized with a minimal bending radius as small as 10 μm by using a standard 220-nm-thick silicon-on-insulator foundry process,and the measured propagation loss is as low as 0.28 dB/cm.Furthermore,the present waveguide spirals are used to realize a 10-bit tunable optical delay line,which has a footprint as small as 2.2 mm×5.9 mm and a dynamic range of 5120 ps with a fine resolution of 10 ps.
