摘要: The aim of the invention is to adjust operating point a laser which can be modulated by data signal. (1) adjusted regulating direct current flowing through (1); whereby said correlates with optical characteristics laser. In order carry out adjustment, . (IBIAS) controlled above an alterable threshold (Ith), possible points are selectably greater for than current. A differential (Idiff) defined from difference between and or variable correlating constant value one solely dependent on temperature adjustment point.
