ABSTRACT:
An optical energy eraser is implemented by the controlled movement of an optical fiber and an optical absorber into close proximity to permit coupling of energy between them. The eraser is used in conjunction with two optical switches to implement a node switch useful for optical fiber networks. An integrated optic implementation permits analogous results by a controlled change in the properties of the region separating a waveguide from an optical absorber so that significant coupling occurs between them.
