A feedback strategy to control the output power and phase of Mach-Zehnder interferometers is presented. The strategy can set an arbitrary working point with >11 bit precision and stability for long-time operation. The use of in-line transparent sensors enables scalability for high-order meshes.

Abstract
A feedback strategy to control the output power and phase of Mach-Zehnder interferometers is presented. The strategy can set an arbitrary working point with >11 bit precision and stability for long-time operation. The use of in-line transparent sensors enables scalability for high-order meshes.File in questo prodotto:
