Title:
ALL-OPTICAL LOGIC GATES AND METHODS FOR THEIR FABRICATION
Document Type and Number:
WIPO Patent Application WO/2010/081019
Kind Code:
A3
Abstract:
The present invention provides optical devices that employ nonlinear optical effects for processing optical signals. For example, such an optical device can include a nano-sized interferometric component that provides an optical output signal via interference of two input signals subsequent to their asymmetric nonlinear phase accumulation. The interferometric element can have a variety of configurations, such as Sagnac, Mach-Zehnder or Michelson configurations.
