  • Direct reference subtraction system for control of optical transmitters
    Patent number: 9191104
    Abstract: An optical measurement system configured to determine whether an optical transmitter signal requires calibration is disclosed. In an implementation, the system includes an optical transmitter configured to emit electromagnetic radiation in limited spectrums of wavelengths at amplitudes based upon one or more transmission signals, and an optical sensor configured to detect the electromagnetic radiation in the limited spectrums of wavelengths and to generate a signal in response thereto. The system includes reference current sources configured to generate a respective reference current and a switch configured to transition between a first configuration and a second configuration based upon the transmission signals. The reference currents are configured to subtract from the signal generated by the optical sensor such that a difference remains.
    Type: Grant
