Telecommunication system based on spatial multiplexing of optical channels

A telecommunications system based on spatial multiplexing of optical channels, comprising:

• an OSCM transmitter system (1) including:
• a data input port (3) to the OSCM transmitter system (1), which receives bits to be transmitted.
• an OSCM modulator system (4), including:
• a processor system (5), which receives the bits to be transmitted from a controller (6) connected to the data input port (3), responsible for mapping the bits to symbols and generating electrical signals necessary to produce an appropriate symbol.
• a spatial modulator (7) containing a series of pixels in which the symbols to be transmitted are modulated;
• a generic light source (8) that generates a beam of light (9) which, when passing through the pixels of the spatial modulator (7), will produce a modulation of each of the channels, generating the symbols to be transmitted;
• an optical transmitter system (10) configured to maximise a signal power in the OSCM modulated optical channel multiplex to the OSCM receiver system (2);
• a communication channel (11);
• an OSCM receiver system (2) containing:
• an optical receiver system (12) configured to create an image of the OSCM spatial modulator (7) on an image sensor (13);
• or, if a diffraction technique has been used in the transmitting optical system, to diffract a received light signal in order to project the received light signal onto the image sensor (13) according to wavelengths of the received light signal;
• and
• an OSCM demodulator system (14), including:
• an image sensor (13) that receives the optical signal from the optical receiver system (12), and extracts the symbols into electrical signals that are sent to a processor system (15);
• and
• wherein the processor system (15) is configured to receive the electrical signals from the image sensor (13) in a time sequence for each of the symbols, and produces a de-mapping process of those symbols to bits which are delivered to a controller (16) of an output port (17) of the OSCM receiver system (2) data.
