Optical interconnection device

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.
