A high sidelobe suppression ratio of 30 dB has been obtained on the submicrometer silicon-on-insulator platform using a CMOS-compatible photonics process with 193 nm lithography. }, URL = {http://www.opticsinfobase.org/ol/abstract.cfm?uri=ol-38-16-3068}, author = {Wei Shi and Han Yun and Charlie Lin and Jonas Flueckiger and Nicolas A.
