Symmetric Mach-Zehnder all-optical device

摘要

The Mach-Zehnder type all-optical device for controlling a signal light with a control light, includes two arms for constituting a Mach- Zehnder configuration, each of the arms being constituted at least partially of material having third order optical nonlinearity, and an introducer of a control light to a portion of each of the arms revealing the optical nonlinearity.
