2025

Abstract

An optical interconnection device (1) comprising a plurality of input/output ports (2) comprising a plurality of receiving ports (2a) and a plurality of transmitting ports (2b), a light routing system (4) comprising at least one spatial light modulator (10) and a control system (20) configured to control the light routing system (4), wherein the optical interconnection device (1) is configurable to receive optical signals from the plurality of receiving ports (2a) and transmit said optical signals to the plurality of transmitting ports (2b) according to a first target set of interconnections comprising a first plurality of interconnections from at least one of the receiving ports (2a) to at least one of the transmitting ports (2b), wherein the control system (20) is configured to generate a first plurality of modulation patches (11) and display said first plurality of modulation patches (11) on the at least one spatial light modulator (10), wherein the first plurality of modulation patches (11) are configured to impose a plurality of successive spatial modulations on light beams (19) received by the receiving ports for routing said light beams (19) from the receiving ports (2a) to the transmitting ports (2b), thereby creating the first plurality of interconnections.

Optical communication

Optical communication, also known as optical telecommunication, is communication at a distance using light to carry information. It can be performed visually or by using electronic devices. The earliest basic forms of optical communication date back several millennia, while the earliest electrical device created to do so was the photophone, invented in 1880. An optical communication system uses a transmitter, which encodes a message into an optical signal, a channel, which carries the signal to its destination, and a receiver, which reproduces the message from the received optical signal.

Optical networking

Optical networking is a means of communication that uses signals encoded in light to transmit information in various types of telecommunications networks. These include limited range local-area networks (LAN) or wide-area networks (WAN), which cross metropolitan and regional areas as well as long-distance national, international and transoceanic networks. It is a form of optical communication that relies on optical amplifiers, lasers or LEDs and wave division multiplexing (WDM) to transmit large quantities of data, generally across fiber-optic cables.

Control system

A control system manages, commands, directs, or regulates the behavior of other devices or systems using control loops. It can range from a single home heating controller using a thermostat controlling a domestic boiler to large industrial control systems which are used for controlling processes or machines. The control systems are designed via control engineering process. For continuously modulated control, a feedback controller is used to automatically control a process or operation.
