Systems for switching optical signals are disclosed. Such a system may include a splitter and a plurality of polarizing filters. The splitter may be configured to receive emitted light and duplicate the emitted light into a plurality of light copies. Each polarizing filter may have a polarization and may be operably connected to the splitter. In addition, each polarizing filter may be configured to receive at least one of the plurality of light copies, filter the at least one of the plurality of received light copies such that light having a similar polarization as that of the polarizing filter passes through the polarizing filter, and output one of a plurality of outputs.

System architecture for an optical switch using wavelength, fiber and polarizaton addressing

A system for transmitting data packets over a network. The system includes a plurality of first nodes, wherein each first node has a first transceiver configured to transmit a data packet at at least one of a plurality of first wavelengths and receive a data packet at an assigned first wavelength, wherein each first node is configured to pass incoming data packets not transmitted at the assigned first wavelength, a plurality of second nodes, wherein each second node has a second transceiver configured to transmit a data packet at least one of a plurality of second wavelengths and receive a data packet at an assigned second wavelength, wherein each second node is configured to pass incoming data packets not transmitted at the assigned second wavelength, and at least one optical fiber operably connecting the transceivers.

Optical network systems and methods for operating same

Methods and systems for using a wavelength as an address in an optical network are disclosed. In particular, methods for selecting a wavelength for a particular node in an optical network, resolving a wavelength for a destination node in an optical network from a network address, and receiving and transmitting data packets at particular wavelengths are disclosed. A resulting system implementing such methods may significantly reduce space, weight and power measurements while transferring data at high rates for a data network.

Method and system for interconnecting end systems over an optical network

A videophone. The videophone can include an imaging mechanism for taking a video picture of a scene. The videophone can include a mechanism for producing a first video stream of the scene and a second video stream of the scene from the video picture and sending the first video stream and the second video stream onto a network at the same time, the producing mechanism in communication with the imaging mechanism. The videophone can include a mechanism for receiving a plurality of video streams of different scenes from a network. The videophone can include a mechanism for displaying the different scenes of the plurality of video streams alongside each other. A method for a video call.

Videophone and method for a video call

An imaging apparatus. The apparatus includes a display mechanism for displaying an image. The apparatus includes a camera mechanism distributed throughout the display mechanism to take images of objects in view of the display mechanism. A screen. The screen includes a display for displaying an image. The screen includes a plurality of pinholes distributed in the display. The screen includes a plurality of sensors with at least one sensor of the plurality of sensors in alignment with and corresponding with one pinhole of the plurality of pinholes to receive light passing through the pinhole to image a ray of a specific size and a specific direction out from the display. A method for imaging.
