Patent number: 6807329Abstract: This application describes an optical switching method for selectively directing an input beam to at least one of two output channels. The input beam impinges on a polarizing beam splitting surface, splitting the input beam into two beam components of different polarizations propagating along different optical paths. These beam components then pass through a controllable polarization rotating medium which selectively affects the polarization of each of the beam components. The beam components are then directed back onto the polarizing beam splitting surface again, producing at least one output beam which propagates toward at least one selected output channel, depending on the state of the medium. The polarizing beam splitting surface is fabricated on a block of the controllable polarization rotating medium, and the input beam also passes through the medium before being split into two beam components by the polarizing beam splitting surface.Type: GrantFiled: July 17, 2001Date of Patent: October 19, 2004Assignee: CIVCOM Devices & Systems Ltd.Inventors: Zeev Zalevsky, Naim Konforti, Efraim Goldenberg, Gal Shabtay, Yehuda Miron

Publication number: 20030021519Abstract: A method and device are presented for carrying out all-optical switching by directing an input beam towards at least one selected output channel. The input beam interacts with a polarizing beam splitting surface, and is therefore split into two beam components of different polarizations. The two input beam components passes through a controllable polarization rotating medium capable of affecting the polarizations of the beam components, when in an operative mode of the medium, and allowing the beam components propagation with unchanged polarizations, when in an inoperative mode of the medium. The beam components passed through said medium are directed towards said polarizing beam splitting surface to thereby produce at least one output beam propagating towards the at least one selected output channel.Type: ApplicationFiled: July 17, 2001Publication date: January 30, 2003Applicant: CIVCOM INC.Inventors: Zeev Zalevsky, Naim Konforti, Efraim Goldenberg, Gal Shabtay, Yehuda Miron
