摘要：

We present compact crossings for silicon-on-insulator photonic wires. The waveguides are broadened using a 3 mu m parabolic taper in each arm. By locally applying a lower index contrast using a double-etch technique, loss of confinement is reduced and 97.5% transmission (-1.7 dB) is achieved with only -40 dB cross talk.
