Abstract: An automatic laser power control circuit comprises a laser diode package, a voltage adjusting unit and a polarity adjusting unit. The laser diode package emits laser light according to an applied voltage, and outputs an electric signal of a voltage proportional to the power of the emitted laser light. The voltage adjusting unit adjusts the voltage applied to said laser diode package based on the voltage of the electric signal outputted from said laser diode package. The polarity adjusting unit changes a polarity of the voltage of the electric signal outputted from said laser diode package so that the polarity is the same as that of the voltage applied to said laser diode package, and supplies the voltage having the changed polarity to said voltage adjusting unit. The automatic laser power control circuit provides an advantage that a monitor diode included in the laser diode package can be compatibly used regardless of its ground type.

Abstract: A method of adjusting an electronic function implemented in an article that forms a part of a population of articles to be adjusted, the electronic function presenting dispersion from one article to another. When necessary, the method comprises replacing an initial parameter stored in a dispersion correction stage that is coupled to the electronic function with a correction parameter so that the combined response of said function plus the associated correction stage to a predetermined input stimulus lies in a predetermined range. The initial parameter is a centered parameter corresponding to the mean value of the capability curve of correction parameters for the function, the mean value itself being updated whenever the percentage of the population of articles for which test measurements lie outside the predetermined range becomes greater than a predetermined percentage. A large proportion of the measurements performed thus lie within the predetermined range so there is then no need to adjust the function.
