  • Patent number: 11949455
    Abstract: An optical communication system may include microLEDs for use in communicating data between chips or multi-chip modules. The number of microLEDs may be greater than a number of electrical data lines for carrying data to be communicated. Signals on the electrical data lines may be inverse multiplexed, for example to allow for operation of the microLEDs at a rate slower than operation of electrical circuitry generating signals on the electrical data lines.
