英文摘要 | Optical transmission is accomplished with a set of transmitter arrays that are each constructed to transmit spatially separated optical data streams that are determined by the positions of each transmitter of said transmitter array and a set of receiver arrays, each of which is constructed to receive one or more of the spatially separated optical data streams. Optical coupling is provided over transmitter and receiver fiber-optic cables and other conventional optical elements, such as lens and prisms, to provide optical paths that maintain the spatial separation of said optical data streams as established by said transmitters. An interface is coupled to transmitters and to receivers which are constructed (i) to translate electrical data signals into optical data streams which are intended to be transmitted from the transmitters to selected receivers and which contain receiver selection data that specifies the selected receivers, and (ii) to prevent any of the transmitters from transmitting to any particular receiver that is selected by a particular transmitter to receive data while that particular receiver is still receiving an optical data stream from another of the transmitters that previously selected that particular receiver. The optical transmitters are implemented with vertical cavity surface emitting lasers (VCSEL) 2-dimensional arrays consisting of an NxN matrix of 30 microns diameter optical emitters with the optical transmitters consisting of a complementary NxN 2-dimensional photodiode array. The photodiode array would use 80 micron diameter oversized detectors to minimize tolerance requirements. |
