US Patent:

6987900, Jan 17, 2006

Filed:

Jul 19, 2004

Appl. No.:

10/894320

Inventors:

Tomasz Leonczuk - San Jose CA, US
Samuel Chang - Redwood City CA, US
Krzysztof Pradzynski - Santa Clara CA, US
Charles Barker - Sunnyvale CA, US

Assignee:

Aurora Networks, Inc. - Santa Clara CA

International Classification:

G02B 6/28

US Classification:

385 16, 385 15, 385 24

Abstract:

Systems and methods are described for optically powered optically controlled optical switches. A method includes powering an optical switch with a communications data signal; and controlling the optical switch with the communications data signal. An apparatus includes a primary optical input port; a secondary optical input port; an optical tap coupled to the primary optical input port; an optical switch coupled to the optical tap and to the secondary optical input port; an optical-to-electrical signal converter coupled to the optical tap; a control circuit coupled to the optical-to-electrical signal converter and to the optical switch; an electrical energy storage circuit coupled to the control circuit; an optical-to-electrical power converter coupled to the electrical energy storage circuit and to the optical switch; and an optical output port coupled to the optical switch, wherein the optical-to-electrical signal converter can transform, to electrical energy, optical energy from a communications data signal that arrives at the optical tap.
