ABSTRACT:
A high-linearity light source comprising a first semiconductor diode (e.g., a light-source diode such as a laser diode or a light-emitting diode, or a light-receiving diode such as a photodetector) and a nonlinearity compensation network with a second, compensation, semiconductor diode is provided. The first and second diodes are connected in an antiparallel configuration with either an A.C. signal source (for light emission) or a load (for light receiving) and in separated D.C. bias paths.
By varying the relative biasing of the diodes (e.g., using a variable resistor in series with a diode), the capacitance of the combination of diodes cancels, and the linearity of the system improves. With a properly biased compensation diode the even-order nonlinearity distortion can be cancelled completely.
